Answer:
Step-by-step explanation:
2. 24^2+7^2 = 625
V 625 = 25
3. 6^2 + 5^2 = 25 +36 = 61
V 61 =7.81024967 =7.8
4. 4^2 +9^2 = 97
V 97= 9.84885780 = 9.8
5. 2^2 +3^2 = 13
V 13 =3.60555127 =3.6
and done!
Answer:
About 1,237 cubic feet.
Step-by-step explanation:
The first step is to know the formula for the volume of a cylinder.
V = pi * r^2*h
You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:
V = pi * 7.5^2 * 7
Divide both sides by 8.5 to get b on its own
68/8.5 = 8
So b = 8
