Circumference: 6.28 feet ~rounded to the nearest hundredth
To find circumference, multiply the diameter by pi.
Area: 3.14 feet squared ~rounded to the nearest hundredth
To find area, divide the diameter by 2 and multiply by pi.
The answer is -8/2 or choice B.
Rewrite the function as:
y = -2/3x
Switch the variables x & y:
x = -2/3y
Solve for y:
x *-3/2 = -2/3y *-3/2
-3x/2 = y
So, the inverse is:
f^-1(x) = -3x/2
Answer:
i think you can just divide
Step-by-step explanation:
To find the number of soccer balls that would be needed to cover the distance to the goal, you will need to find the diameter of the soccer ball.
To find the diameter use be formula for circumference to solve for the diameter.
C = pi x d
28 = 3.14 x d
d = 8.9 inches
The distance to cover is 24 feet, so convert to inches and divide by 8.9 inches.
24 x 12 = 288 inches
288/8.9 = 32.4 balls
You will need about 32 soccer balls to cover the distance.
