Your answer is the last option, 615.44 ft³.
We know this as the formula for the volume of a cone is [(π × r²) × ]/3, and substituting in our numbers, with 3.14 being π, we get:
[(3.14 × 7²) × 12]/3 = (153.86 × 12)/3 = 1846.32/3 = 615.44
I hope this helps!
Hey!
The formula for finding volume of a cone is: (π · r² · h) ÷ 3
[tex] \pi = 3.14 [/tex]
[tex] r = 7 \\ r^{2} = 7 \times 7 = 49 [/tex]
[tex] h = 12 [/tex]
First multiply
[tex] 3.14 \times 49 \times 12 = 1846.32 [/tex]
Divide by 3
[tex] 1846.32 \div 3 = 615.44\ ft^{3} [/tex]
Your answer is the last choice
Good luck and hope this helps! :)
