Aballoon has a circumference of 23 cm. use the circumference to approximate the surface area of the balloon to the nearest square centimeter. a. 1,662 cm2 b. 529 cm2 c. 168 cm2 d. 674 cm2

Area = 42.062184.

Step-by-step explanation:

Given : A balloon has a circumference of 23 cm.

To find : Use the circumference to approximate the surface area of the balloon to the nearest square centimeter.

Solution : We have given circumference of 23 cm.

circumference = 2 * pi * radius.

23 = 2 * 3.14 * radius.

23 = 6 .28 * radius.

On dividing by 6.28 both sides

radius = 3.66 cm.

Area = pi * radius².

Area = 3.14 * ( 3.66)².

Area = 3.14 * 13.3956

Area = 42.062184.

Therefore, Area = 42.062184.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
