The surface area of a sphere with a diameter of 7cm is 153.9cm2
18 CM
Surface area of the sphere = 4*pi*92 = 1017.87602 or about 1018 sq cm
Using the formula for the surface area of a sphere, which is SA = 4 (pi) r2, you can find the radius, and the diameter of the sphere is twice the radius. Example: If the surface of a sphere is 380 square cm 4 (pi) r2 = SA 4 (3.1416) r2 = 380 12.5664 r2 = 380 r2 = approx. 30.24 r = 5.5 and diameter D = 11 cm
60 cm diameter sphere area = pi x 602 cm2 = 11310 cm2 = 1.131 m2
Surface area of sphere: 4*pi*7^2 = 196*pi square cm
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere whose diameter is 18cm is 1018cm2
18 CM
The sphere's diameter is 3.921 cm
18 CM
The surface area is 804.25 cm2
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
Surface area of the sphere = 4*pi*92 = 1017.87602 or about 1018 sq cm
Surface area = 4*pi*72 = 615.752 square cm to 3 decimal places
A sphere with this volume has a diameter of 9.1416 cm, a surface area of 262.54 square cm and a circumference of 28.719 cm.
Using the formula for the surface area of a sphere, which is SA = 4 (pi) r2, you can find the radius, and the diameter of the sphere is twice the radius. Example: If the surface of a sphere is 380 square cm 4 (pi) r2 = SA 4 (3.1416) r2 = 380 12.5664 r2 = 380 r2 = approx. 30.24 r = 5.5 and diameter D = 11 cm
60 cm diameter sphere area = pi x 602 cm2 = 11310 cm2 = 1.131 m2
