i dont know how to find the radius

2.5 cm

Step-by-step explanation:

Since they give you the height of the button, it is the same as the diameter.  The diameter is 2 as big as the radius so, we need to divide 5 by 2 to get the radius.

Example:  The diameter is 6, find the radius

To find the radius, divide 6 by 2

6 / 2

3 is the radius

The Actual Problem:  

Step 1:  Find the radius by dividing 5 by 2

5 / 2

2.5 cm is the radius

 2.5 cm

The height of the circle can also be classified as the diameter. The radius of a circle is the length of the midpoint to the end of the circle. The radius is half the diameter, so, we can divide.

5 / 2 = 2.5cm. is the radius

Best of Luck!

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
