What is the area of the beach ball with a diameter of 14 in. ?

Juliette [100K]

Answer:

The answer is 675.75 square Inches

Step-by-step explanation:

<h3><u>Given</u>;</h3>

Diameter (d) = 14 in.

Area of beach ball = ?

<h3><u>Formula</u>;</h3>

Area = 4πr²

Now,

Radius (r) = diameter ÷ 2

r = 14/2 in.

r = 7 in.

Now,

A = 4πr²

A = 4 × 22/7 × (7)² in.

A = 4 × 22 × 7 in.

A = 615.75 square in.

Thus, The area of the beach ball with a diameter of 14 in. is 615.75 square in.

The median is the middle of a list of numbers from least to greatest.
I will set up the numbers from least to greatest for you.
5, 6, 6, 8, 9.
To determine the median, cross out the smallest number with the largest number until you can no longer do so.
5, 6, 6, 8, 9.
6, 6, 8.
6.
Your median is 6.

Person a can paint the neighbor's house 22 times as fast as person

Levart [38]

Let 1/x=the time it takes for person b to paint
let 1/22x the time that it takes for person a to paint
lastly we have the following since we know that when they work together that is how long it takes
$\frac{1}{x} + \frac{1}{22x} = \frac{1}{77}$
to solve we first multiply both sides by 1694x
$1694 + 77 = 22x$
we then combine like terms
$1771 = 22x$
lastly we divide both sides by 22
$80.5 = x$
