What is the surface area of a sphere that has a radius of 5 cm? Use 3.14 for . Round to the nearest tenth.
To find the surface area of a sphere, you can use the formula:
Surface Area = 4 * π * r^2
Where:
π is a mathematical constant approximately equal to 3.14, and
r is the radius of the sphere.
Given that the radius of the sphere is 5 cm, we can substitute this value into the formula:
Surface Area = 4 * 3.14 * (5 cm)^2
Simplifying the expression:
Surface Area = 4 * 3.14 * 25 cm^2
Surface Area = 314 cm^2
Therefore, the surface area of a sphere with a radius of 5 cm is approximately 314 cm^2.
To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
where π is a mathematical constant approximately equal to 3.14, and r is the radius of the sphere.
In this case, the radius of the sphere is given as 5 cm. Plugging this value into the formula, we have:
Surface Area = 4 * 3.14 * (5 cm)^2
First, let's square the radius: (5 cm)^2 = 25 cm^2
Now, we can substitute this value into the formula:
Surface Area = 4 * 3.14 * 25 cm^2
Performing the calculations:
Surface Area = 314 cm^2
So, to the nearest tenth, the surface area of the sphere with a radius of 5 cm is approximately 314.0 cm^2.
