Question

The circumference of a circle is about 37.7 cm and the diameter is about 12 cm. What expression best represents the value of π ? Question 3 options: 6/37.7 12/37.7 37.7/6 37.7/12

Answer 1

Answer:

Step-by-step explanation:

Circumference of a circle means the perimeter of a circle and it is given be

Perimeter=2πr

P=2πr

Though π is a constant

But this question want us to find π

Make π the subject of the formula

Then, divide both side by

π=P/2r

Given that P=37.7cm

And diameter =12

And radius is half of diameter.

Therefore, radius =12/2=6cm

Then

π=P/2r

π=37.7/2×6

π=37.7/12.

Then, the last option is the correct option
