Use 3.14 for Pi and round to the nearest tenth.
Find the surface area of a sphere with a radius of 8 cm.
A)267.9 cm2
B)803.8 cm2
C)2143.6 cm2
D)201.0 cm2
Is it B?
To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
Where π (pi) is approximately 3.14, and r is the radius of the sphere.
In this case, the radius is given as 8 cm.
Plug the values into the formula:
Surface Area = 4 * 3.14 * (8 cm)^2
Surface Area = 4 * 3.14 * 64 cm^2
Surface Area = 804.16 cm^2
Since we need to round to the nearest tenth, the closest value is 803.8 cm^2.
So the correct answer is B) 803.8 cm^2.
