5. Use 3.14 for π to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary.
Answers
Step-by-step explanation:
the radius of a circle is half of the diameter
= 24.4/2 = 12.2 m
the area of a circle is
pi × r²
r being the radius.
so, in our case that is
3.14 × 12.2² = 3.14 × 148.84 = 467.3576 ≈ 467.36 m²

A deck of cards has 52 cards.
There are 4 suits, diamonds, hearts, clubs and spades. Each suit has 13 cards.
What is the probability that I will randomly pick a 2, put it back, then randomly pick a 4?
Answers
Answer: [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
The probability that you get a 2 is [tex]\frac{4}{52}[/tex] and that simplifies into [tex]\frac{1}{3}[/tex]. It is the same probability that you get a 4 because you put the 2 back. [tex]\frac{1}{3}[/tex] x [tex]\frac{1}{3}[/tex] = [tex]\frac{1}{9}[/tex],
The eggs of birds and other animals come in many different shapes and sizes. Eggs often have a shape that is nearly spherical. When this is true, you can use the formula for a sphere to find their volume.
Fossilized spherical eggs of dinosaurs called titanosaurus sauropods were found in Patagonia. These eggs were 11 centimeters in diameter. Find the volume of an egg. Round your answer to the nearest tenth.
Answers
Answer:
696.9 cm^3 to the nearest tenth.
Step-by-step explanation:
Radius of the egg = 1/2 * 11 = 5.5 cm.
Volume = 4/3 * pi * 5.5^3
= 696.9099703

The height of statue of liberty is 93 meters.
Step-by-step explanation:
Given : Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1 inch : 6.2 meters.
To find : Which equation can Howard use to determine x, the height in meters, of the Statue of Liberty?
Solution :
The model is 15 inches tall.
The scale of the model to the actual statue is 1 inch : 6.2 meters.
Let x be the height in meters of the Statue of Liberty.

A rectangle’s perimeter is 28 meters and its area is 46 square meters. How long is its
longest side, in meters?
Answers
Answer:
I'm not sure but I think that it is 10.5
Step-by-step explanation:
The longest side is 8.73 meters long
Given that area of rectangle is 48 square meters and perimeter is 28 meters, we need to find the longest side length
What is perimeter and area of a rectangle?
Perimeter = 2(L+B)
Area=L×B
2(L+B)=28
L+B=14....(1)
LB=46....(2)
L=46/B (From2)
Put the value of L in (1)
46/B+B=14
B^2-14B+8=0
By solving above equation we get B=8.73
substitute value of B in 1
L+8.73=14
L=5.27
Therefore longest side in meters is 8.73

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?
2 1/2 feet
4 1/2 feet
3 3/4 feet
1 1/4 feet
Answers
Answer:
4 1/2 ft
Step-by-step explanation:
1 yard = 36 inches
2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches
The board started with a length of 72 inches.
He used 18 inches.
72 in. - 18 in. = 54 in.
He has 54 in. left.
Now we convert 54 in. to ft.
1 ft = 12 in.
54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

Answer: 240 Miles
Step-by-step explanation:
My answer is correct because, if 1 cm =15 miles and the distance is 16 cm apart, then all we have to do is multiply 16 times 15 (since there are 15 miles in 1 cm and theres 16 cm.) 15 x 16=240 so the naswer is 240 Miles!
Hope This Helps!
Answer:
240 miles.
Step-by-step explanation:
First, you are going to determine the ratio of centimeters to miles (1:15)
Since there are 15 miles to every centimeter, you may create an equation like this to help: 15 x c = m (m being miles and c being centimeters)
This means that for every centimeter there are 15 miles.
Since the distance between Town A and Town B is 16 centimeters, you may replace the variable "c" with 16 like so: 15 x 16 = m
Because there are 15 miles for every centimeter, you may multiply the centimeters by 15 to get the distance, using the aforementioned equation of 15 x 16 = m. 15 times 16 is 240.
Therefore there are 240 miles separating Town A and Town B.

So for any designated number 1-6 = (p) = 1/6
Step-by-step explanation:
When there is just one event there will always be 6 possible outcomes for one number, so the number of favorable outcomes will be divided by 6 to get your probability.
A) 2 can occur 1 time. P(2) = 1/6
B) there are 3 even numbers. P(even) = 3/6 = 1/2
C) 4 or 5 are 2 possible outcomes. P(4,5) = 2/6 = 1/3
D) there are 3 odd numbers. P(odd) = 3/6 = 1/2
So for any designated number 1-6 = (p) = 1/6
