Question

The height of cylinder is $7cm$ its radius is $5cm$ find its Total surface area and Curved surface area

Answer 1

The height of cylinder is $7cm$

The radius of cylinder is $5cm$

The Curved surface area is

$2\pi rh$

$2\times \frac{22}{7}\times 5\times 7=220c{m}^2$

The total surface area is $2\pi rh+2\pi r^2$

$220+2\times \frac{22}{7}\times 25220+157.14285=377.14285c{m}^2$
