Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.

Using the information in the problem you have:

A= PI x 15^2

A = PI x 225

A = 706.5 sq. In.

Answer:

A =706.5 in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We are given the diameter

r = d/2 = 30/2 = 15

A = pi * 15^2

A = pi*225

We can approximate pi by 3.14

A = (3.14)*225

A =706.5 in^2

A jet ski company charges a flat fee of $24.00 plus $2.25 per hour to rent a jet ski. Another company charges a fee of $23.00 pl

Tju [1.3M]

Let

x----------> charge per hour to rent a jet sky in dollars

y----------> the total cost to rent a jet sky in dollars

we know that

First Jet Sky Company

$y=24.00+2.25x$ ---------> equation $1$

Second Jet Sky Company

$y=23.00+2.50x$ ---------> equation $2$

we know that

To find the number of hours for which the costs are the same

equate equation $1$ and equation $2$

The intersection both graphs is the solution of the problem

using a graph tool

see the attached figure

the intersection point is $(4,33)$

That means

For $x=4\ hours$

the cost of the rent is $y=\$33$ in both companies

therefore

the answer is

$4\ hours$
