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.

we need the options

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
