Question

calculate the surface area of sphere whose volume is 4851cm^3

Answer 1

Answer

given volume =4851 cm^3

so, we have to find first the radius and then only could find surface area of sphere

so the steps are as follows=

the volume of sphere=4/3(22/7)(r^3)

4/3(22/7)(r^3)=4851

r^3=4851=> (4/3)*π*r3 = 4851    (r is the radius of sphere)

=> {(4*22)/(3*7)} *r3 = 4851     (π = 22/7)

=> r3 = (4851*3*7)/(4*22)

=> r3  =  101871/88

=> r3  = 1157.625

=> r = 3√1157.625

=> r = 10.49 cm

so the suface area =
