Question

A sphere has a volume of V=3600 in cubed. Find it’s surface area

Answer 1

1136.6cm^2

Explanation:

`V = 3600\\V =(4)/(3) \pi* r^3\\3600=(4)/(3) * (22)/(7) * r^3\\3600 =(88r^3)/(21) \\88r^3 =3600 * 21\\88r^3 =75600\\(88r^3)/(88) =(75600)/(88) \\r^3 = 859\\\sqrt[3]{r^3} =\sqrt[3]{859} \\r = 9.51\\\\T.S.A = 4\pi* r^2\\T.S.A = 4 * 3.142* 9.51^2\\T.S.A = 4 * 3.142 * 90.4401\\T.S.A = 4* 284.16\\T.S.A =1136.64`
