PI QUESTION COME FOR BRAINLIEST

19·64 square inches

Step-by-step explanation:

Area of a circle = πr²

= 22/7 × 1·25 × 1·25

=4·91 square inches × 4

= 19·64 square inches

4.9

Step-by-step explanation:

Assuming the question is asking for the area of the circles (but both answers are below in case it means the space around the circles)

So to find the total area of the whole square, 5x5=25.

To find the area of one circle, use the equation A=pi(R)^2

If the diameter is 1.25, then the radius will be 1.25/2, or 0.625.

A=pi (0.625)^2

A=1.22718...

This is the area of one circle. Multiply it by 4 to get area of all circles.

A=4.9 (or round it to 5)

to find the area of the space around the circles, just do 25-4.9.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
