Answer:
Step-by-step explanation:
volume= (pi)(radius^2)(h)
252(pi)=(pi)(radius^2)(7)
divide both sides by pi
252=(radius^2)(7)
divide both sides by 7
36=(radius^2)
square root each side
6=radius
1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:
22/7(16^2) = about 805 meters squared.
2. Let's find the area of the rectangle first.
A=LW
A= 18(10)
A= 180 cm squared.
Now the semi-Circle:
The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:
22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:
127 cm squared for the semi-circle.
Now we add up the rectangle and semi-circle's areas:
180 + 127 = 307 cm squared as your answer.

Answer:
The fraction of the money that Lisa received will be 5x/13
Step-by-step explanation:
The the amount shared by Lisa and ant be x
If Lisa and ant share the money in the ratio 5:8, to get the fraction Lisa received;
Step1:
The total ratio will give:
5+8 = 13
Since the ratio Lisa got was 5, then the fraction of money Lisa receive will be:
Lisa ratio/Total ratio × Amount shared
= 5/13 × x
= 5x/13
Therefore, the fraction of the money that Lisa received will be 5x/13
