We are given with the equations for the volume of the sphere and area of the sphere such as shown below:
Volume of sphere = 4/3 r³
Area of the sphere = 4r²
We need to solve for the area if radius = 1 inch and the solution is:
Area of the sphere = 4(1)²
Area of the sphere = 4 inch²
The answer is 4 inches².

The angles are x =25, angle A = 20 and B = 70
<h3>How to solve for the angles?</h3>
The given parameters are:
A = x - 5
B = 2x + 20
Both angles are complementary angles.
This means that:
x - 5 + 2x + 20 = 90
Evaluate the like terms
3x = 75
Divide both sides by 3
x = 25
Substitute x = 25 in A = x - 5 and B = 2x + 20
A = 25 - 5 = 20
B = 2 * 25 + 20 = 70
Hence, the angles are x =25, angle A = 20 and B = 70
