Step-by-step explanation:

1/3 times pie times radius squared times height

1/3 x 3.14 x 4^2 x 20

Answer 2

Correct Question :

Determine the volume of the cone to its nearest tenth of a unit.

Solution :

As we know,

$volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h$

Given dimensions of cone are :

Height (h) =20ft

Radius (r) =4ft

$volume \: of \: a \: cone = \frac{1}{3} \pi \times {4}^{2} \times 20 \: \: {ft}^{3}$

$volume \: of \: a \: cone = \frac{1}{3} \times \pi \times 16 \times 20 \: {ft}^{3}$

$volume \: of \: a \: cone = 335.1 \: {ft}^{3}$

Now on rounding off to the nearest tenth of a unit we get,

Volume of cone =340 ft³.
