Question

The Curved Surface Area of a cylinder is 176cm^2 and its base area is 38.5cm. Find the volume of the cylinder.​

Answer 1

$Volume of cyclinder= pi * r^2 * hArea of base=area of circle= pi*r^238.5=22/7*r^238.5*7/22=r^2269.5/22=r^212.25=r^2or, r= 3.5 cmC.S.A of cylinder= 2 pi r h176 =2*22/7*3.5*h 176*7/2*22*3.5 = hor, h=8Volume of cylinder= pi r^2 h=22/7*(3.5)^2*8=308 cm^3.$
