Answer:

r ≈ 22.44 ft

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ), then

141 = 2πr ( divide both sides by 2π )

$\frac{141}{2\pi }$ = r , that is

r ≈ 22.44 ft ( to the nearest hundredth )

Step-by-step explanation:

plug it in

circumference = 2 x Pi x r

141 = 2 x 3.14 x r

141 = 6.28 x r

141 ÷ 6.28 = r

22.45 = r

For every 3 wrapped packages Mary uses 1/2 roll of wrapping paper how many packages can she wrap with 2 1/2 rolls of wrapping pa

8_murik_8 [283]

Answer:

15 packages

Step-by-step explanation:

Set up a proportion, where x is the number of packages she can wrap with 2.5 rolls of wrapping paper:

$\frac{3}{0.5}$ = $\frac{x}{2.5}$

Cross multiply and solve for x:

0.5x = 7.5

x = 15

So, with 2.5 rolls of wrapping paper, she can wrap 15 packages

Use the pythagorean theorem.

a^2 + b^2 = c^2

a = 20ft

c = 28ft

400 + b^2 = 784

b^2 = 384

b = 19.596
