Answer:
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.
Hope it helps you....

Step-by-step explanation:
SA=4πr²
TSA= Area of curved surface + area of open surface
TSA=¼*4*π r²+½π r² +½π r²
=π r² +πr²=2π r²
