Answer:
$5,671.84
Step-by-step explanation:
To find the third side, we can use the law of cosines:
c^2 = a^2 + b^2 - 2ab*cos(theta)
c^2 = 157^2 + 157^2 - 2*157*157*cos(65)
c^2 = 28463.7649
c = 168.71 feet
The perimeter of the playground is:
P = 157 + 157 + 168.71 = 482.71 feet
If each foot costs $11.75, the final cost is:
Cost = 482.71 * 11.75 = $5,671.84
Answer:
1944 inche^2
Step-by-step explanation:
18*18 = 324 each face
324*6 = 1944
Answer:
It's the first one
Step-by-step explanation:
Answer:
A = 3.14
Step-by-step explanation:
Area = π r^2
Circumference = 2π r
- A = C^2/4π
- 6.28^2/4•π ≈ 3.13841
