IDK

Explanation:

sorry

Answer 2

the circumference of Clare's circle is 75 cm

Explanation:

The circumference of a circle is the length of its perimeter.

Let's define circumference as "C". We can calculate the circumference of a circle with following formula:

`C=\pi*d`

where π is pi, and d is diameter.

Then, to know Priya circle diameter;

`C=\pi *d\\25cm=3.14*d\\d=25cm/3.14\\d=7.96`

Clare's circle has a diameter of 3*7.96=23.88cm

Next we calculate the circumference of Clare's circle:

`C=\pi *d\\C=3.14*23.88cm\\C=75cm`
