300 parents
3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
Circumference C=2pi*r
But in question C=40pi
This implies that 2pi*r=40pi
This implies that r=20 in.
d=2*r=40 in.
Hope this helps :)
