Anybody know the answer ?

C=2πr
 We have 3/4 of circumference
 (3π/2)*2π=3/4.
 and it is equal 5π/2.
(3/4)*C=(3/4)*2πr
5π/2 = 6πr/4
5/2=6r/4
r=(5/2)*(4/6)=(5*4)/(2*6)=5/3
r=5/3

A bolt has 16-1/2 turns per inch. How many bolts would be in 2-1/2 inches?
ohaa [14]

Answer:

41 1/4

Step-by-step explanation:

Change 16  1/2 to a mixed number

16 1/2 = (2*16+1)/2 = 33/2

Change 2 1/2 to a mixed number = (2*2+1)/2 = 5/2

Multiply the turns per inch by the inches

33/2 * 5/2 =165/4

Change this back to a mixed number

4 goes into 165 41 times

41*4 = 164   there is 1 left over

41 1/4
