Can someone please help me solve this i cant figure it out and no one will answer my question

The perimeter is (81.681409) cm.  The area is (530.929158) cm squared.

***don't know what your answers are...round if you need to***

Step-by-step explanation:

Finding the circumference (or perimeter) C = 2 π r

C = 2 * 3.142 * 13

C = 26π

C = 81.681409 cm

Finding the area A = π r²

A = π * 13²

A = 169π

A = 530.929158

step-by-step explanation:

i think you should think about the question and not look online.

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
