What is the surface are of a sphere with radius 2?
The surface area of a sphere with a radius of 2 is about 50.27 units2
What is the ratio of the surface area of a sphere with radius 2 ft to the surface area of a sphere with radius of 5 ft?
a. 2 to 5.
What is surface area of spherical shell?
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
What is the surface area of a sphere with a radius of 2?
SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
How do you calculate the surface area of a spherical tank with a diameter of 96 inches?
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
What is the surface area of a sphere with a radius of 10 meters?
The surface area of any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .
What is the surface area of the sphere with 12 units in length?
Surface area of a sphere = 4*pi*radius^2
What happens to the surface area of a sphere if its radius is doubled?
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
What is the surface area of sphere with radius 13ft?
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
What is the surface are of a sphere with a radius of 4.75?
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
If the radius of a sphere doubles does its surface area double?
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
The circumference of a hollow ball is 29cm What is the surface area?
2 x pi x radius = circumfrance 2 x pi x radius = 29 29/ 2pi = radius radius = 4.62 (3 sig.fig.) 4 x pi x radius^2 = Surface area of sphere 12.56 x radius^2 = Surface area of sphere 12.56 x 4.62^2 = Surface area of sphere 268 cm2 (3 sig.fig)
