The answer is 36π or approximately 113.1 cm.
314.28571 cm.
Surface area = 4*pi*32 = 36pi square cm
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 10 cm, the surface area is4 (3.1416) (10)2 = 4 (3.1416)(100) = about 1256.64 cm2
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
The sphere's diameter is 3.921 cm
The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area of a sphere with a radius of 42cm is about 22,167cm2
314.28571 cm.
Surface area of sphere: 4*pi*7^2 = 196*pi square cm
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Surface area = 4*pi*32 = 36pi square cm
Surface area = 4*pi*142 = 784pi square cm
Surface Area = 4*pi*r2 = 6566.9 sq cm
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 10 cm, the surface area is4 (3.1416) (10)2 = 4 (3.1416)(100) = about 1256.64 cm2
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
The surface area is about 314.16 cm2The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 cm, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 cm2*Do not confuse the sphere's surface area formula SA = 4 (pi) r2 withthe formula for the volume of the sphere, which is V = 4/3 (pi) r3
It is: 4*pi*62 = 144*pi square cm
