Answer:
A. 1206 cm³
Step-by-step explanation:
We have a cone and are asked to find the approximate volume of it.
Keep in mind we are using π for 3.14
The forumla of a cone is V = πr²
We know the radius = 12
and the height = 8
Substitute :
V = π12²
Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:
V =
Cancel the common factor - 3 :
V =
Multiply 8 and 3π :
V =
Solve the exponent :
V =
Multiply :
V =
Multiply for the final answer :
1205.76 cm³
which can be rounded up to
A. 1206 cm³
