Answer:
A:
Step-by-step explanation:
Side length ratios in a 30°-60°-90° "special" triangle are (shortest to longest):
1 : √3 : 2
Comparing to the given side lengths, we have ...
1 : √3 : 2 = x : 20 : y
Making these ratios the same gives ...
x = 20/√3 = (20√3)/3
y = 2x = (40√3)/3
These values match choice A.
X^2 + 13x + 42
What two numbers multiplied equal 42 and if added equal 13?
Given:
The area of the given sphere = 36π in²
To find the volume of the given sphere.
We need to find the radius first.
Formula
- The area of a sphere
- The volume of the sphere
where, r be the radius of the sphere.
Now,
According to the problem,
or, [ Eliminating π from both the side]
or,
or,
or,
So,
The radius of the sphere is 3 inches
Therefore,
The volume of the sphere is
or,
Hence,
The volume of the sphere is 36π cube inches.
