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.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
