Answer:
- 615.8 square feet
- 9 truckloads
Step-by-step explanation:
The area of the circular ring is given by the formula ...
A = πr²
where r is the radius, or half the diameter.
A = π(14 ft)² = 196π ft² ≈ 615.752 ft²
The area of the training area is about 615.8 square feet.
__
The number of truckloads of dirt required for coverage will be ...
(615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads
Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.
Answer:
Given a function f ( x ) \displaystyle f\left(x\right) f(x), a new function g ( x ) = − f ( x ) \displaystyle g\left(x\ right)=-f\left(x\right) g(x)=−f(x) is a vertical reflection
Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in
Circumference of circle= 2πr so, 2×5×π= 31.4 in
Use the Pythagorean Theorem
a^2 + b^2 = c^2
a and b are the legs, and c is the hypotenuse
You have 10 and 13 for the legs so
10^2 + 13^2 = c^2
Simplify
100 + 169 = c^2
269 = c^2
c is about 16
