Answer:

D. 100.5 in³

Explanation:

We know that:

Volume of obligue cone = ⅓*area of base* height

Here

slant t=10in

height =6 in

Let's find the radius:

By using Pythagorous theorem,

slight height²=diameter²+height²

substituting value

10²=diameter²+6²

diameter²=10²-6²

diameter²=64

diameter=
√(64)=8 in

Therefore, Radius= diameter/2=8/2=4 in

Now

Area of Base= πr²=π*4²=50.265

Now

Volume = ⅓*area of base*height =⅓*50.265*6=100.53 in³

So,

Volume of obligue cone is 100.5 in³
