A manhole cover has a radius of 12 inches what is the diameter of the manhole cover?

1 answer:

3 0

The diameter of a circle is the distance across at its widest point (right through the center). The radius is the distance from any point on the circle to the center (which means it's half of the diameter. Since we know the radius of the manhole cover is 12 inches then...

diameter = 2 × r
diameter = 2 × 12
diameter = 24 inches

How do you do question 22

Alborosie

Answer:

∠YXZ = 58°

Step-by-step explanation:

Use the angle sum theorem and the given relations.

∠WXY +∠WXV = ∠YXV

∠WXY +(11° +3∠WXY) = 139°

4∠WXY = 128° . . . . . subtract 11°

∠WXY = 32° . . . . . . . divide by 4

Similarly, ...

∠WXY +∠YXZ = 90°

∠YXZ = 90° -∠WXY = 90° -32°

∠YXZ = 58°
