There are no close answers, because you decided
not to list the choices at all.

The area of a circle is (pi) x (radius²) .

So    80 = (pi) (radius²)

Divide each side by pi : Radius² = (80/pi)

Take the square root
of each side:       Radius = √ (80/pi)

       = 5.0463 cm (rounded)

A customer bought a car and paid $1,080 in sales tax.The rate is 6%?

Ghella [55]

The price of car is $18000

Step-by-step explanation:

Given

Sales tax on car = $1080

Rate = 6%

Let x be the price of the car

We know that as the rate of sale tax is 6%, 6% of x is 1080

Using mathematical notation

0.06x = 1080

Dividing both sides by 0.06

$\frac{0.06x}{0.06} = \frac{1080}{0.06}\\\\x = 18000$

Hence,

The price of car is $18000
