If its radius is 6, then the surface area of the sphere is: 4*pi*6*6 = 144*pi square units.

The surface area of the sphere is ~452.4 square units.

approximately 452.39 feet

SA = 4pi62

True... Good luck with Apex :)

Use the formula 4 x pi x radius2.

It is: 4*pi*62 = 144*pi square cm

It is: 4*pi*62 = 144*pi square meters

1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.

It is: 4*pi*62 = 452.389 square feet to three decimal places

Surface area of a sphere equals 4 times Pi times the Square of its radius. So plugging in the needed radius of 6 makes the formula Area=4*pi*R^2 or 4*pi *6^2 or 4*36*pi and with pi=3.141592654... this becomes 452.3893421... units (144*3.141592654...)

Radius: 6/(2*pi) = 0.9549296586 Surface area: 4*pi*0.95492965862 = 11.4591559 or as 11.459 square cm to three decimal places
