Answer:
67.5π m²
Step-by-step explanation:
See the diagram given with the question.
The angle moved by the radius line about the center to cover the shaded region is 300°.
As the radius(r) is known to be 9 m.
So, the area of the full circle is πr² = π × (9)² = 81π m².
Now, to cover the whole circle the radius line has to rotate 360° about the center.
Hence, for rotation of 360° the area obtained is 81π m².
Then for rotation of 300° the area obtained will be 
m². (Answer)
Answer:24
Step-by-step explanation:35% of 24 is 8.40 so round that you will get your answer
Diameter d=16cm
d=r/2=8cm
Volume V(sphere)=4/3*pi*r^3
Therefore volume V=2145.52 cm^3
Hope this helps!
Answer:
D. Step 1 only.
Step-by-step explanation:
Here, Josie didn't use the distributive property correctly. The other two steps are still right, so D is correct.
How it should have been done:
x + 3 + 7x(x - 5)
<em>Use the distributive property to multiply 7x by x - 5.</em>
x + 3 + 7x² - 35x (The boldened part is what should have happened for Step 1)
<em>Combine x and -35x to get -34x.</em>
7x² - 34x - 3 is what the earlier equation should be simplified to.
