The formula of an area of a circle with radius r:

Part A.
We have diameter of the circle d = 8 in. The diameter of a circle is equal two times length of a radius.
Therefore:

Calculate the area:

Answer: C. 16π square inches.
Part 2.
Look at the picture.
Total area:

Answer: C. 36π square inches
Answer:
r =2.9985yd
Step-by-step explanation:
Given that the circumference of a circle is 2
r
where r is the radius and
= 3.1415926....
You have
2
r = 18.84 yd
2(3.1415926)r = 18.84 yd
6.2831r = 18.84yd
divide through by 6.2831
r = 2.9985yd = aprox 3yds
Answer:
Step-by-step explanation:
The 6x^2 because 6 is not a perfect square.
Answer: 41
Explanation: Use the equation. If you put the x value, which is 5, into the equation, you can solve.
4(5)+21
4 x 5 is 20
20+21=41
hope this helps!!
