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

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
