Awheel has a radius of 12 cm. find the circumferencec=2* 3.14* rfind approximately how far does it travel in 2 revolutions.(a.) 47.1 cm(b.) 150.72 cm(c.) 188.4 cm(d.) 376.8 cm

Result: Circumference = 150.72cm

Explanation:

To find the circumference, C, we will use this formula:

C = 2 * 3.14 * r

Substitute:

C = 2 * 3.14 * 12

Multiply:

2 x 12 = 24

24 x 3.14 = 75.36

And since the question asked for two revolutions.

All we need to do is multiply 75.36 by 2:

75.36 x 2 = 150.72

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
