Answer:

C = 2pi mm or approximately 6.28 mm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

C = 2 * pi *1

C = 2pi

We can approximate pi by 3.14

C = 2*3.14

C =6.28 mm

Answer:

The circle's circumference is 2 pi ml

Step-by-step explanation:

The formula for the circumference of a circle is 2 $\pi$ r, or diameter times pi.

In this case, we simply plug into the equation. Using the formula 2 $\pi$ r, we get 2(1) $\pi$ , or 2 $\pi ml$

Answer:

Given : PQ = RQ

to find : angle B

PQ = RQ
Angle B = angle QRP ( angle opposite to equal side are equal). ...(1)
angle QRP + 140° = 180° ( linear pair)
angle QRP = 180° - 140°
angle QRP = 40°
from equation (1)
Angle B = angle QRP = 40°

Hello There!

An example of this would be:
$\frac{6}{1/4}$
6 = $\frac{6}{1}$
$\frac{6}{1} * \frac{4}{1}$
= $\frac{24}{1}$
= 24

Hope This Helps You!
Good Luck :)
