This is the concept of area of solid materials, we are required to calculate the total area of horsehide that is required to cover 100 balls with each having a circumference of 9 in.
The area of hide required will be given by:
area=(area of each ball)*(total number of balls)
area of each ball is given by:
SA=4πr^2
given that the circumference is 9in, we are required to find the radius of the ball
Circumference, c=2πr
thus;
9=2πr
r=9/(2π)
r=1.4 in
Therefore the surface area will be:
SA=4π*1.4^2=24.6 in^2
Therefore the area of horsehide required to cover 100 balls will be:
Area=24.6*100=2,460 in^2.
Answer:
This true because why ?
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Evaluate the function. f(x) = 4x2 + 4x - 4 Find f(3)
f(3) = 4 x 2 + 4(3) - 4
After this step conduct PEMDAS
f(3) = 4 x 2 + 12 - 4
f(3) = 8 + 12 - 4
f(3) = 20 - 4
f(3) = 16
