Question

Consider the circles shown. Circle A has a diameter of 6 centimeter. Circle B has a diameter of 25% greater than Circle A

Determine the circumference for Circle B. Use 3.14 for pi.

Answer 1

23.5 cm

Explanation:

Step one:

Given data

Circle A has a diameter of 6 centimeter

Circle B has a diameter of 25% greater than Circle A

Step two:

Let us find the diameter of circle B

25% of 5 is given as

=25/100*6

=0.25*6

=1.5 cm

Circle B

= 6+1.5

= 7.5 cm in diameter

radius= 7.5/2= 3.75cm

We know that

Circumference= 2πr

C= 2*3.142*3.75

C=23.5 cm
