Question

The volume of a cylinder is 225 cm and its height is 9 cm.

Answer 1

Answer:

The radius of the cylinder is 2.82 cm.

Step-by-step explanation:

The volume of a cylinder is computed using the formula:

$Volume=\pi r^{2}h$

Here r is the radius and h is the height.

Consider the diagram below.

The volume is 225 cm³ and height is 9 cm.

Determine the radius as follows:

$Volume=\pi r^{2}h\\r^{2}=\frac{Volume}{\pi \times h} \\r=\sqrt{\frac{Volume}{\pi \times h}}\\=\sqrt{\frac{225}{3.14\times 9} } \\=2.8204\\\approx2.82 cm$

Thus, the radius of the cylinder is 2.82 cm.

None of the provided options is correct.

Answer 2

Answer:

It’s none of the above over here, since the radius is 2.82
