Question

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km.

Answer 1

Answer:

Volume of the volcano is 130 km³. Option A.

Step-by-step explanation:

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km.

We have to calculate the volume of the volcano.

As we know the formula of volume of a cone = (1/3)πr²h

Now by putting the values of radius and height of cone.

Volume = (1/3)π×(8)²×(1.95) = $\frac{(3.14)(64)(1.95)}{3}=130$

Therefore the answer is Option A. 130 km³

Answer 2

The answer should be 130km^2
