The answer is 6 because 13-7 is 6
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:
11.35 hrs
Step-by-step explanation:
13627.482 liters in 3600 gallons÷ by 20 to get how many minutes it would takeand then divide by 60 to reduce your answer into hours.
Answer:
Step-by-step explanation:
Given
f(x) = 
Finding f(-1) means, we have to put -1 in the places of x in the function,
So, putting x=-1 in the function
As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,
=> 
=> 1
Hence,
Hi! The answer is 231.25.
The answer is 231.25 because 8,325 / 36 is 231.25 I hope this helped! Goodluck :)
