Answer:
5) a. 43in sqaured
6) a. 200.96 m sqaured
Step-by-step explanation:
5) Find the area of one of the circles first. Area = 3.14 times radius sqaured so the eqaution would be a= 3.14*5*5 which would equal 78.5, For both of the circles, the area would be 78.5 in sqaured. Add them together for both of the circle's area to get 157 inches sqaured. To find the area of the entire rectangle, you can see that 1/4 of the rectangle is 5 inches so if you add 5 together 4 times it would be 20 in, so the length would be 20 inches. For the height it would also be 5 but since its only 5 inches for 1/2 of the rectangle, it height would be 10. 20 times 10 for get the area of the rectangle, which is 200. Then subtract the circles's area by the enitre area to get 43 inches sqaured.
6) The formula to find area of a sqaure is pi times radius sqaured. The eqaution would be a=3.14*8*8. The answer would be 200.96 so the answer is 200.96 sqaured.
I hope this helped and just a reminder that diameter is not the same as raduis sqaured. If the question gives you a diameter, you have to divide the number by 2 to get the raduis then contiune on with the eqaution. Please correct me if I'm wrong though:)
