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:
(-5,-6)
Step-by-step explanation:
Let(-3,-9)=(x1,y1)
(-7,-3)=(x2,y2)
Using midpoint formula,
Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)
=((-3+(-7))/2,(-9+(-3))/2))
=((-3-7)/2),(-9-3)/2))
=((-10/2),(-12/2))
=(-5,-6)
Thus midpoint(x,y)=(-5,-6)
Answer:
Answer should be choice 4
Step-by-step explanation:
This is the volume of the sphere & is not at all a linear function.
A linear function of the form of y=kx (k is a given number/coefficient) where
y & x grow at the same rate. Then whatever the input (x) it will generate an output (y) always in the ration y/x, whereas v=4/3 πr³ (coefficient =k =4/3(π), if r increase by 2 units v will increase by 2³ =8 & for r = 3, v increase by 3³ =27.
In short v increases quicker than r. No it's not a linear function
