Avani is building a rectangular play area. the length of the play area is 7.5 meters. the width of the play area is 5.3 meters. if she wants to cover the area in foam, how much foam does she need to buy?
due to the accuracy of the tape measure avani used, the amount of foam needed to cover the play area is?

Avani will need to buy 39.8 meter² foam.

Step-by-step explanation:

Length of the rectangular play area is = 7.5 meters

Width of the play area is = 5.3 meters.

Now we have to calculate the amount of foam to cover this play area

Therefore area of the rectangle = Length × width

Area = 7.5 × 5.3 = 39.75 meter²

So the answer is 39.8 meter² foam will be required to cover the rectangular play area.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
