<span>
it consists of a rectangle, dimensions L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2
</span>then, you have one half of the area of the circle that has diameter R = 3ft - radius will be r = 1.5ft the area of that half will be:
Ac = r^2

/ 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2
= 7.065 ft^2/ 2
= 3.5325ft^2
A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2
<span>At the rate of $2 per square foot, the cost will be:
$ 15.5325*2 = 31.07 </span>
115/29 should work for your problem
Answer:
7. 16
8. 8
9. 8
10. 12
11. 12
12. 18
Step-by-step explanation:
The centroid cuts each median into parts in the ratio 2:1. This fact can be used to find the desired lengths.
7. SH = 2/3×SM = 2/3×24 = 16
8. HM = 1/3×SM = 1/3×24 = 8
9. TH = 2×DH = 2×4 = 8
10. HR = 2×EH = 2×6 = 12
11. TD = TH +DH = 8 +4 = 12
12. ER = EH +HR = 6 +12 = 18
