Question

I need help with only 5 and 6

Answer 1

Answer:

5.  D

6.  15 feet

Step-by-step 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 $3\frac{3}{4}$

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

$r=\frac{3\frac{3}{4}}{2}=\frac{\frac{15}{4}}{2}=\frac{15}{4}*\frac{1}{2}=\frac{15}{8}$

Now, the circumference (c):

$c=2\pi r=2\pi (\frac{15}{8})=11.78$

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 $3\frac{3}{4}$ feet.

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

$3\frac{3}{4}=\frac{15}{4}$

Now,

$\frac{15}{4}+\frac{15}{4}+\frac{15}{4}+\frac{15}{4}=\frac{60}{4}=15$

The amount of cloth needed on square is 15 feet

There is no correct answer choice.
