Step-by-step explanation:
The formula to calculate the surface area of a sphere is the following:
Where A is the area of the sphere and r is the radius of the sphere.
In this case we know that the diameter d of the sphere is:
The diameter is:
.
Thus
Then the surface area of the sphere is:
Answer:
A. 15
Step-by-step explanation:
Hypotenuse = 22
Since the two angles other than the 90° are both
45° , it means that the two legs of the right triangle are of equal length.
So, (x)²+ (x)² = 22²
2x² = 22²
x² = 484/2
x² = 242
x = √242
x = 15.55
x ≈ 15
We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50
The man will make $3,187.50 if he sells 30 parts.
