3pi/2 or roughly 4.7

Step-by-step explanation:

quarter circle's perimeter = 10.71 cm

Step-by-step explanation:

Given the radius we can solve for the circumference of the whole circle.

The circumference formula is: C = 2 * 3.14 * r

We can plug in r with 3 as it is given.

C = 2 * 3.14 * 3

Now we solve for C.

C = 18.84 cm

That is the perimeter of the whole circle. Since it only asks for a quarter we can divide this 18.84 by 4 to get a quarter of the circumference. Which will be the curved edge. So the curved edge is 4.71 cm now add the radius for each straight side for a total of 6 cm to the 4.71 to find the total perimeter.

The total perimeter is 10.71 cm

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
