Find the radius of a sphere whose surface area is 154 cm2
Answer Details
The surface area of a sphere is given by the formula:
A = 4πr^2
where A is the surface area and r is the radius of the sphere.
In this problem, we are given the surface area of the sphere, which is 154 cm^2. We can use this information to find the radius of the sphere.
We start by rearranging the formula to solve for r:
r = √(A/4π)
Plugging in the value of A = 154 cm^2, we get:
r = √(154/4π) ≈ 3.5 cm
Therefore, the radius of the sphere is approximately 3.5 cm.
So, the correct answer to this problem is option B: 3.50 cm.
