First use distrib. property of mult.

18x - 72 = 5x -7
18x-5x = -7+72
13x = 65
13/13x = 65/13
x = 5

HELP What is the area of a circle with a radius of 13 feet? IT IS NOT 530.93 ft ​
NeTakaya

Answer:

530.66

Step-by-step explanation:

to find the area you need to do pi times the radius square and to find the radius squared you just times it by its self so 13 times 13 which is 169 and pi is 3.14

so now you just do 3.14x169=530.66
