Answer:
4187 cm^3
Step-by-step explanation:
The diameter is 20
radius = d/2 = 20/2 = 10
The volume is
V=4/3 pi r^3
= 4/3 pi (10)^3
Using pi = 3.14
= 4/3 (3.14) 1000
=4186.6666666
Rounding to the nearest whole number
4187 cm^3
Answer:
12 people!
Step-by-step explanation:
each pizza is cut into 4 pieces, and there are 3 whole pizzas. 4 times 3= 12!
Subtract the smaller amount ($23.04) from the larger ($29.40), and then divide the difference by 12 pounds:
$6.36
-------- = $0.53 / lb
12 lb
Answer:
20ft
Explanation:
You multiply the model length by the scale factor to find the actual length. <u>If the scale factor is less than zero, then the actual size will be smaller than the model</u>. Therefore, your answer would be 20ft.
Specifically, the scale factor is .8 if the actual size is 20ft, 1 if the actual size is 25ft, and 1.2 if the actual size is 30ft.
