Question

the capacity of a closed cylinder is 141.3 cm³ its height is 5 cm find its: radius and total surface area​

Answer 1

height= 5 cm

therefore volume =π r^2 h

22/7 * r^2 * 5

110r^2/7cm^3

but the volume is 141.3 cm^3

therefore 110r^2/7=141.3

110r^2=141.3*7

110r^2= 9891

r^2=9891/110

r=√9891/110
