Question:
What is the volume of this right cone?
40π cm³
300π cm³
400π cm³
480π cm³
The image of the cone is attached below:
Answer:
Option c: 400π cm³
Explanation:
It is given that a right cone with radius = 10 cm , height = 12 cm and lateral height 15.6 cm
To determine the volume of the right cone, let us substitute these values in the formula,
Thus, we get,
Multiplying the terms,
Dividing by 3, we get,
Thus, the volume of the cone is 400π cm³
Hence, Option c is the correct answer.
The equation to find volume is V=
r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.
