Answer:
A. The area is [tex]78.54m^2[/tex]
B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool
Step-by-step explanation:
Question A:
Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.
Since we know this, we can easily find the area of the circle using [tex]\pi r^2[/tex]
Area of the circle = [tex]\pi \times 5 \times 5 = 78.54m^2[/tex]
Question B
Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.
We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.
The area of the circle can be calculated using [tex]\pi r^2[/tex]
Area of circle = [tex]\pi \times 23 \times 23 = 1661.9ft^2[/tex]
Andrew sold 60 baseball cards to a friend . This was 80% of Andrews total baseball card collection. How many total baseball cards where in Andrews collection ?
Answer:
75
Step-by-step explanation:
We know that 80% of Andrew's (former) baseball card collection is 60. Thus, We divide 60 by 80% (equal to 0.8) to obtain [tex]\frac{60}{0.8}=75[/tex].
Answer:
In total there were 75 cards in Andrews collection.
Step-by-step explanation:
We know that 60 is 80% of the total amount of cards Andrew has. Therefore, all we have to do to find the total number of baseball cards is to divide 60 by 80 to find 1% and then multiply the result by 100 to get 100% (the total amount of cards). And so we get...
60 / 80 x 100 = 60 / 0.8 = 75

[tex] {6}^{2} \times \pi \times 15 + \frac{1}{2} \times \frac{4}{3} \times \pi \times {6}^{3} = 19 \times {6}^{2} \times 3.14 = 2147.76[/tex]
Answer:
Step-by-step explanation:
Hemisphere Formula: ( 2 / 3 ) πR = V
Substitution: ( 2 / 3 ) 3.14 * 6 = 12.56
Cylinder Formula: πR^2 * H = V
Substitution: 3.14 * 6^2 * 15 = 1695.6

What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Cost of lunch = $23
Sales tax= 9%
Tip= 20%
So, amount after sales tax
= 23 + 9% of 23
= $ 25.07
and, the amount after tip
= 23+ 4.6
= $27.6
Thus, she paid a total of
= 27.6 + 25.07
= $52.67
