surface area of a spere=4*pie*r2 when r (radius)=5 pie=22/7 surface area=4*22/7*5*5 =2200/7 =314.2 dm2

It is 2*(7*4 + 4*2 + 2*7) = 100 square cm.

Surface Area = 4*pi*r2 = 49*pi so that r2 = 49/4 and so r = 7/2 = 3.5 Then Volume = 4/3*pi*r3 = 343/6*pi = 179.6 cm3.

Volume is 4/3 pi*radius*radius*radius 3.14 times 7 times 7 times 7 times 4 divided by 3= volume 1436.2666666 Surface area is 4 * pi * radius * radius 4 times 3.14 times 7 times 7=surface area 615.44
