Step-by-step explanation:
Hello There!
First thing we want to do is find the formula for circumference of a circle
C = 2(3.14)r
where r = radius
we are given the diameter so we have to convert that into radius to do so we just divide by 2
42/2=21 so the radius equals 21 inches
now we just plug in 21 for r in the formula

So we can conclude that the circumference of the circle is 131.88 inches
3/4 times 5=
5 times 3=15
15/4=3 3/4
3 3/4 is answer
