➷ The formula for circumference is \pi d

1) \pi d = 31.4

Divide both sides by \pi

d = 9.99 (consider this to be 10)

Half this to find the radius

10/2 = 5

It would be figure B.

2) \pi d = 37.68

Divide both sides by \pi:

d = 11.99 (consider this to be 12)

Divide by 2 to find the radius:

12/2 = 6

It would be figure C.

3) area = \pi r^2

\pi r^2 = 153.86

r^2 = 48.97515909

r = 6.998 (consider this to be 7)

It would be figure D

4) \pi r^2 = 113.04

r^2 = 35.98174

r = 5.998 (consider this to be 6)

It would be figure C.

5) radius = diameter / 2

radius = 3

\pi (3)^2 = 28.27433

It would be option C

An algebra book weighs 6 oz less
Mashcka [7]

Answer:

Algebra book weighs 24 oz

Grammar book weighs 15 oz

Step-by-step explanation:

algebra = x and grammar = y

x = 2y-6

5x = 8y

5(2y-6) = 8y

10y - 30 = 8y

2y - 30 = 0

2y = 30

y = 15

x = 2(15)-6

x = 30-6

x = 24
