Question

The radius of circle is 7ab- 7 bc-14ac find the circumference of circle

Answer 1

Answer:

Perimeter = 2×22/7×(7ab-7bc-14ca)

= 44/7×7(ab-bc-2ca)

= 44×(ab - bc - 2ca)

= 44ab - 44bc - 88ca

Answer 2

circumference = 2 x π x r
= 2 x 22/7 x(7ab-7bc-14ca)
=44(7ab-7bc-14ca)/7
=44 x 7(ab-bc-2ca)/7
=44ab-44bc-88ca
