Question

A plate has a diameter of 14 inches . what is the approximate circumference of the plate?

a) 21.98 in
b) 43.96 in
c) 87.92 in
d) 153.86 in

Answer 1

circumference formula is 2(pi)r^2
so you need to find the radius(diameter/2) r=7
then multiply 7 x 3.14= 21.98
then multiply by 2 21.98 x 2= 43.96
answer is B 43.96
