kicyunya [14]

Answer:

B

Step-by-step explanation:

A cylinder is like circles staked on top of each other so you want to find the are of the top circle which is 28.26 because pi r^2 (3^2)*3.14. now you found the area of the top circle. The height is 10.5 so that means there are 10.5 layers so you multiply 28.26 by 10.5 i know its confusing im new to brainly but hopefully this answer helped you You will get 296.73 because i rounded pi to 3.14 but the answer is B

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

olga_2 [115]

Answer:

$7\pi cm^2$

Step-by-step explanation:

The area of a circle is given by $A=\pi r^2$

For circle B, the radius is 3 cm, it has an area of $\pi *3^2=9\pi cm^2$

Circle D also has a radius of 1 cm. Its area is $\pi *1^2=\pi cm^2$

Circle P also has a radius of 1 cm and area $\pi*1^2=\pi cm^2$

The area of the shaded region is then $9\pi -\pi-\pi=7\pi cm^2$
