Step-by-step explanation:
find the volume of the upper left part by finding the dimensions
it already gives 2 side lengths: 2 and 2. To find the 3rd side length you can take 5 - 2 to get 3. 3*2*2 = 12
find the volume of the bottom portion by finding the dimensions. we are given 2 sides again: 2 and 2. to get the upper long side, we can do 4 + 2 to get 6. 6*2*2 = 24
24+12= 36cm^3

Sharon is buying a circular rug for her room. The diameter of the rug is 8 feet which measurement is closest to the area of the rug in square feet
Answers
Answer:
50.24 feet²
Step-by-step explanation:
Given that:
Diameter of circular rug = 8 feets
To obtain the area of the circular rug, we use the formula for the Area of a circle = πr²
A = πr²
r = Radius of circle = diameter / 2 = 8 /2 = 4 feets
Area of circular rug = π * 4²
Area of circular rug = 3.14 * 16 = 50.24 feet²

Step-by-step explanation:
3000 divided in 8 slices is 375 calories per piece.
3 pieces with 375 cals per 1125
Answer:
1125 calories
Step-by-step explanation:
Find how many calories are in one slice by dividing 3000 by 8:
3000/8
= 375
Find how many calories are in 3 slices by multiplying 375 by 3
375(3)
= 1125
So, in 3 slices of pizza, there are 1125 calories
Dale and 2 friends share one fourth of a cake. Each piece is the same size. Dale believes each piece of cake has an angle measure of 45°. Is Dale correct?
Answers
Answer:
dale is not correct
the correct angle is 30 degrees
Step-by-step explanation:
A cake is shaped like a circle
the total sum of angles in a circle is 360 degrees
If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees
If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees
the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong
Answer:
dale is incorrect
