Question

CSA of right circular cylinder is 440 cm square and the radius of its circular base is 7cm find the volume of the cylinder

Answer 1

Step-by-step explanation:

CSA Of a cylinder= 2πrh

2πrh=440cm^2

2×22/7×7×h=440

22×2×h=440

44×h=440

h=440/44

h=10cm

Volume of a cylinder= πr2h

=22/7×7×7×10

=22×7×10

=154×10

=1540cm^2

(I hope this is correct)
