The answer is 10. Hope this helps!
Answer:
690.8 in^2
Step-by-step explanation:
First find the area of the three circles, by doing 3.14 r^2
With the innermost circle, 3.14 6^2 --> 113.04
With the second circle, 10 inches + 6 inches (inner circle radius), 3.14 16^2 --> 803.84.
With the outermost circle, you don't need it for the problem.
Then, we do subtraction to find the area of the shaded region, removing the "dount hole".
803.84 - 113.04 = 690.8 in^2
Answer:
12 and 7 meters
Step-by-step explanation:
The area is 84 square meters and the width is 5 meters less than the length. 12 is the length and 7 is the width. 7 is 5 less than 12, and 12*7=84.
The length is 12 and the width is 7
Answer:
The last answer is correct.
Step-by-step explanation:
If plug 5 into the equation in place of R(radius) then u get 392.69. The you round and you get 392.7. You get 125 from doing 5^3. The pi after 125 is being multiplied which gets you 392.7.
