Question

find the total surface area of a sphere and a hemisphere of same radius?​

Answer 1

Answer:

TSA of sphere = 4πr^2

TSA of hemisphere= 3πr^2

There ratio will be 4πr^2:3πr^2

= 4:3.

Answer 2

Answer:

$\huge{\underline{\underline{\mathfrak{answer}}}} \\ sphere = 4 \: \pi \: r \: ^{2} </p><p> \\ hemisphere = 3\pi \: r {}^{2}$
