A circular light fixture has a radius of 20 centimeters. what is the circumference of the light fixture

Step-by-step explanation:

Circumference can be found by multiplying the diameter of the circle by pi.

We are given the radius, which is 20 centimeters. We need the diameter, which is twice the radius.

Substitute the diameter into the formula. There are many ways to calculate circumference, so I included a few options.

1. In Terms of Pi

If we solve in terms of pi, we leave π in the answer.

2. Using 3.14 as Pi

Substitute 3.14 in for pi.

3. Using 3.14159 as PI

Use the pi button on a calculator.

The circumference of the light fixture is 40π, 125.6 cm, or 125.6637061 cm

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
