Question

if a lemon of radius R is divided into four identical parts then what would be the total surface area of the four parts the the option is (a-2 pai r square, b-4 pai r square , c-6 pai r square , d- 8 pai r square

Answer 1

The surface area of a sphere is :

SA = 4πr²

The lemon is spherical.

When it is divided into four parts, we will get the area of a quarter a sphere.

TSA = Area of curved surface + area of open surface.

TSA = 1/4 × 4 × πr² + 1/2πr² + 1/2πr²

= πr² + πr² = 2πr²
