Answer:
$2310
Step-by-step explanation:
Total cost of fencing = area of fence x cost of fencing per feet
Area of a circle = nr^2
n = 22/7
r = radius = 7
Area = 22/7 x 7^2 = 154
154 x 15 = 2310
Answer:
4.39 to 2DP.
Step-by-step explanation:
x * (x - 2) = 28
x^2 - 2x = 28
Solving by completing the square:
(x - 1)^2 - 1 = 28
(x - 1)^2 = 29
x = +/-√29 + 1
x = 6.38516, -4.38516
x must be positive so it = 6.38516.
The shortest side = x - 2 = 4.385.
