Find the area of a circle with a circumstance of 37.68

The area of the circle is 113.04

Step-by-step explanation:

To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of circumference of a circle and we will clear the radius

c = circumference  = 37.68

r = radius

π = 3.14

c = 2π * r

r = c / 2π

we replace with the known values

r = 37.68 / (2 * 3.14)

r = 37.68 / 6.28

r = 6

Now that we have the radius  we need to use the area formula of a circle:

a = area

r = radius = 6

π = 3.14

a = π * r²

we replace with the known values

a = π * 6²

a = π * 36

a = 113.04

The area of the circle is 113.04

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
