Question

Find the TSA of a quadrant of a sphere of Radius `r'​

Answer 1

Step-by-step explanation:

• Here, Radius = r
• So, Total surface area of sphere = 4πr^2 square units

Answer 2

$4\pi r^2$ square units is the total surface area of the quadrant of the sphere.

Quadrant of sphere:

A circle is a stable figure middle from two points a bowed surface specific that all point superficial is the unchanging distance from the centre.  
In other words, a circle is a absolutely round concerning manipulation of numbers object in three-spatial scope, just like a surface of a round globe. The distance from the center to the external surface of circle is named allure range.
The surface district of a circle is delineated as the amount of domain below the surface of a circle and is effective 4πr². The capacity of circle is the room busy by it in 3d room.
The total surface region, in another way, is a blend of the bowed region in addition to the field of the base The formula for the total surface region  and the bent surface extent of the circle is likely beneath.
