Question

These cones are similar find the volume of the smaller cone round to the nearest 10th 2 is the radius

Answer 1

4.2 units^3

Explanation:

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius

h = height

1/3 x (22/7) x (2^2) = 4.2

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
