Question

The curved surface area of a right circular cylinder of height 14cm is 88cm find the diametre of the cylinder

Answer 1

formula πr(h+r)
using this we can find the radius and diameter is double of radius
22/7*x(14+x)=88
14x+xsquare=88*7/22
x square+14x=28
then by factorisation we can find it

Answer 2

i hope this will hep you
