if the total surface area of solid sphere is 98.56cm2‚then find the radius of the sphere.

Answer :

⇒Given :- TSA of sphere = 98.56 m²......... ⇒To find ;- Radius of sphere ?................. ⇒Sol :- TSA of sphere =4πr² =⇒98.56 m² = 4×22/7× r =⇒r = 2.8005634425181 m

Tsa of solid sphere = 4πr²
98.56 = 4 * 22/7 * r²
98.56 * 1/4 * 7/22 = r²
689.92/88 = r²
7.84 = r²
2.8 = r
Radius = 2.8 cm
