Question

What is the approximate volume of a cone with a height of 9 ft and radius of 3 ft?

Use 3.14 to approximate pi, and express your final answer to the nearest tenth.


?? ft^3

Answer 1

Answer:wrong

Explanation:

Answer 2

volume of a cone=1/3 times height times area of base
area of base=area of circle=pi times r^2
r=3
aprox pi to 3.14
height=9

so we have
volume=1/3 times 9 times 3.14 times 3^2
3^2=9
1/3 times 9 times 3.14 times 9
3 times 3.14 time s9
9.42 times 9
84.78
nearest tenth
0.78=0.8

answer is 84.8 ft^3
