21 is the length of the rectangle
Im pretty sure you would go six over and four up
Hope I helped
good luck!!!!
Answer:
16π or 50.3 units
Step-by-step explanation:
the formula for the surface area of a sphere (as you mentioned) is:
4πr²
So if we plug in the given value (2) for r:
4π×2²=16π
Answer:
15 degrees
Step-by-step explanation:
ALL of the angles in the 12 sided polygon will be equal to 150 degrees. You already have Q which is 150 degrees. If you do know that angles in a triangle add up to 180 degrees then you should subtract the angle Q (150 degrees) from 180 and you should get 30 degrees left. This is the total angle of angles P and R. As it is a regular shape, the angles should be equal to each other. This means that both of them would be equal to 15 degrees.
This means angle PRQ is 15 degrees.
