Please answer this correctly. and I will make you the brainest !:)​

Answer 1

Answer:

7 cm.

Step-by-step explanation:

Surface area of sphere = 800 cm²

Surface area of sphere = 4πr²

4πr² = 800

πr² = 200

r² = 200 / 3.14

r² = 63.694267515923566878980891719745

r = 7.9808688446762215213346272711802

Approx = 7 cm.

∴ Radius of sphere (x) = 7 cm.

Answer 2

Answer:

Area of a circle

=pie*r^2

area-800cm^2

then,

πr^2=800

$\sqrt{x = } \sqrt{800} \div \pi$

plz take x as r.

r= root~254.647908947

r=15.9576912161
