Some students are painting a mural of the Earth. They draw a circle with a radius of 8 feet to represent the Earth. Question What is the approximate circumference of the circle? (Use pi equals 3.14) Answer options with 4 options A. 12.56 feet B. 25.12 feet C. 50.24 feet D. 200.96 feet

C. 50.24 feet

Step-by-step explanation:

The formula for circumference is 2rπ (two times radius times pi)

2 * 8  * 3.14 = 50.24

3

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!
