Damari wants to trim the circular concrete mural with outdoor rope lighting. The mural has a
diameter of 45 feet. One rope has a length of 50
ft. Each strand costs $39.99. How much will
Damari spend in order to trim the mural with
rope lighting? Use 3.14 to approximate .

First, let's find the perimeter of the concrete mural.

A circle of diameter d, has a perimeter:

p = d*pi

where pi = 3.14

the concrete mural has a diameter of 45 ft, then it's perimeter is:

P = 45ft*3.14 = 141.3 ft

One rope has a length of 50ft, and costs $39.99.

Let's find the number of ropes that Damari needs to use, so let's divide the perimeter in lengths of 50ft:

N = 141.3ft/50ft = 2.826

Then Damari needs 2.826 ropes, but she can not buy 0.826 of a rope, then we should round it up to 3 ropes.

Then she needs to buy 3 ropes, and she will pay 3 times $39.99, this is:

Cost = 3*$39.99 = $119.97

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
