Answer:
D
Step-by-step explanation:
Use the formula for the SA of a hemisphere.
![SA=2\pi r^2](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E2)
Now we can find the radius of the hemisphere, which is 15.
Then, we can square that and multiply it by 2 to get 450.
Now, let's use the formula for the Volume of a hemisphere.
![V=\frac{2\pi r^3}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B2%5Cpi%20r%5E3%7D%7B3%7D)
Now we can cube 15 and multiply it by 2 to get 6750.
Then we can divide this number by 3.
2250.
So the answer is D.
B because there are 14 in 2/7 as well as 4 divided by 2/7
Based on the definition of an isosceles trapezoid, the measure of angle MQP in the figure shown is: m∠MQP = 73°.
<h3>What is an Isosceles Trapezoid?</h3>
An isosceles trapezoid has the following properties:
- It has two diagonals that are equal.
- It has a pair of opposite sides that are congruent and a pair of opposite sides that are parallel.
- Opposite angles in an isosceles trapezoid are supplementary.
The figure given is an isosceles trapezoid.
The measure of angle MNP is given as 107°.
Angle MQP and angle MNP are opposite angles.
Based on the properties of an isosceles trapezoid, we have:
m∠MQP + m∠MNP = 180
Substitute
m∠MQP + 107 = 180
m∠MQP = 180 - 107
m∠MQP = 73°
