Answer:

12.62 m

Step-by-step explanation:

Area of a circle = πr²

Area = 125m²

Hence:

125m² = πr²

r² = 125m²/π

r = √125m²/π

Hence,

r =√ 39.788735773

r = 6.3078313051 m

Diameter = Radius × 2

Therefore, Diameter of one circle is

= 6.3078313051 m × 2

= 12.61566261m

Approximately = 12.62 m

Answer:

$y=80x+25$

Step-by-step explanation:

Let

x ----> the number of hours

y ---> the total cost of renting a jet ski in dollars

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=\$80\ per\ hour$

we have the ordered pair (3,265)

substitute in the linear equation

$265=80(3)+b$

solve for b

$265=240+b$

$b=265-240$

$b=\$25$ ----> fee for a lesson on how to use the jet ski

substitute

$y=80x+25$
