Question

Find the circumference

Answer 1

90

Explanation:

The Answer will be 90 because Pie is being replaced with 3, so it would be like 2(3)(15) which equals to 90.

But If Pie remains pie the equation would look like (2)(3.14)(15) which would turn out to be 94.2

Answer 2

90 units

Explanation:

circumference C = 2
`\pi`r

taking
`\pi` as 3.

C = 2 × 3 × 15

(15 is the radius of the circle)

C = 90 units
