A wire is bent into form a square of side 22 cm . If the wire is rebent to form a circle , Find its radius

14 cm

Step-by-step explanation:

First, find the perimeter of the square:

22(4)= 88

This means the circumference of the circle will be 88cm.

Use the circumference formula to solve for the radius:

C = 2r

88 = 2r

Divide both sides by 2

88 = 2r

14 = r

So, the radius is 14 cm

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
