Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle= 
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
Answer:
B. 27 inches
Step-by-step explanation:
given s³ = 729 where s is the length of each side of the fish tank (which also happens to equal the height because all sides of a cube are equal length)
s³ = 729
s = ∛729
s = 27 inches
The correct answer is the third option, which is:
6 inches²
The explanation is shown below:
1. You are working with the areas of the pentagons shown in the figure above. Therefore, the ratios are:
side1²/side2²=A1/A2
(7.5)²/(2.5)²=54/A2
Where A2 is the the area of the smaller pentagon.
2. Therefore, you have that the result is:
A2=6 inches² (As you can see, it is the third option mentioned above).
Add the radius of the pool to the width of the path to get the radius of the path (15 + 3 = 18). Using 2(pi)r = Circumference, we get 36(pi). If you multiply 36x3.14 you get 103.4 ft.
3.14 the perimeter is the 4 in 3.14
