Surface area of a sphere = 4*pi*radius2

The surface area of a 14-inch sphere is 615.75 square inches.The formula for the surface area of a sphere is 4*pi*r2 where r=radius

the formula for surface area of a sphere is 4pi(r squared) so do 4x3.14x144 equals 576 pieunits^2

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

The surface area of a sphere can be found with the formula 4pi * r2. Assuming the hemisphere is exactly half of a sphere, the surface area of a hemisphere can be found using the formula A = 2pi * r2 + pi * r2 Which can be written as A = pi(3r2) 942cm/pi = 3r2 314cm/pi = r2 r = 10cm (approximately) The radius of the hemisphere is approximately 10cm.
