A circular clock with a circumference of 88cm is mounted on a wall. How much area of a wall didn't occupy​

616 cm^2

Step-by-step explanation:

Steps to derive the answer

1.we are going to first determine the radius from the circumference

2.we would calculate the area

Circumference of a circle = 2nr

n = 22/7

r = radius

88 = 2 x 22/7 x r

Divide both sides of the equation by 2 x 7/22

r = 14

Area of a circle = nr^2

3.14 x 14^2 = 616 cm^2

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
