Question

find the radius of a cylinder of height 21 cm and volume 3234 cm^3​

Answer 1

Answer:

volume of cylinder=πr^2h=22/7×r^2×21

=3234. 66r^2=3234. r^2=49 r=7cm

Answer 2

Answer:

radius(r) = 7 cm

Step-by-step explanation:

here radius(r) = ? , height(h) = 21 cm

volume = pi * r^2 * h

3234 = 22/7 * r^2 * 21

3234/21 = 22/7 * r^2

154 = 22/7 * r^2

154*7 / 22 = r^2

1078/22 = r^2

49 = r^2

r = 7
