Question

The height of cone is 15 cm volume 1.70 find the radius of base
answer​

Answer 1

Answer:

0.33 cm

Step-by-step explanation:

We know the formula of Volume of a cone is:

$V = \pi r^2\frac{h}{3}$

where, V = volume, r = radius of the base, h = height of the cone.

Given, height of cone is 15 cm and volume 1.70

=> h = 15 and V = 1.7

So, according to the formula:

$1.7 = \pi r^2\frac{15}{3}\\=> 1.7 = \pi r^2 5\\=> r^2 = \frac{1.7}{5\pi}\\=> r = \sqrt{\frac{1.7}{5\pi}} \\=> r = 0.33 (approimately.)$

So, the radius of the cone is 0.33 cm
