Question

the radius of a sphere whose surface area is 17 1/9 cm square​

Answer 1

Step-by-step explanation:

$4\pi \: r {}^{2}$

that the formula of surface area of sphere

given surface area =17 1/9 = 154/9

$4\pi \: r {}^{2}$

then 4×22/7×r^2 =154/9

22/7×r^2 =154/9×4

r^2=154/9×4×7/22

r^2=14×14/3×3

r=root of 14^2/3^2

r=14/3

therefore the radius of sphere =14/3
