Square PQSR is inscribed in circle T. RS = 8_/2.

a. Find the length of the diameter of Circle T.
b. Find the Perimeter of PQSR.
c. Find the Circumference of Circle T.

Look at explanation, and hope it helps. Please mark as brainliest! Take care during these hard time.

Step-by-step explanation:

a.

A diagonal of a square inscribed in a circle is the diameter.

So, to find the diameter we know if we separate the square into two different 45-45-90 degree triangles where a and b is 8. Use the 45-45-90 degree theorem shown in picture to find that the diagonal 8 times equals 16.

So, the diagonal is 16, thus the diameter is 16.

b.

Multiply 8 times 4 to get 32 as the perimeter as there are 4 sides which are equal to RS

c.

The circumference of a circle is the diameter times . The diameter we know from a, which is 16. So, it is 16

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

m∠a is 90°

m∠b is 40°
