Question

I need help with only 5 and 6

Answer 1

5. D

6. 15 feet

Explanation:

5.

The amount of fringe cloth will go around the circular cloth.

We need to find the perimeter of a circle.

Perimeter (aka Circumference) of circle = 2πr

Where r is the radius (half of diameter)

Diameter is given as
`3(3)/(4)`

We convert this to improper fraction and divide by 2 to find the radius:

`r=(3(3)/(4))/(2)=((15)/(4))/(2)=(15)/(4)*(1)/(2)=(15)/(8)`

Now, the circumference (c):

`c=2\pi r=2\pi ((15)/(8))=11.78`

This, rounded to nearest whole number is 12 ft

Answer choice D is right.

6.

The amount of fringe around the square is the sum of all 4 sides with each of them measuring
`3(3)/(4)` feet.

We convert to improper fraction and add them up (4 times):

`3(3)/(4)=(15)/(4)`

Now,

`(15)/(4)+(15)/(4)+(15)/(4)+(15)/(4)=(60)/(4)=15`

The amount of cloth needed on square is 15 feet

There is no correct answer choice.
