What is the diamater of a circle<br> the area of a circle is 144π m^2
nadya68 [22]

Answer:

24 meters

Step-by-step explanation:

The area of a circle can be found using the following formula.

a=\pi r^2

We know that the area is 144pi m^2.

a= 144\pi m^2

Substitute 144pi m^2 in for a.

144\pi  m^2= \pi r^2

We want to find the diameter. First, we must find the radius. We have to get the variable, r,  by itself.

Divide both sides of the equation by pi.

144\pi  m^2/ \pi = \pi r^2 / \pi

144\pi  m^2/ \pi =  r^2

144 m^2= r^2

The variable, r , is being squared. The inverse of a square is the square root. Take the square root of both sides of the equation.

\sqrt{144 m^2} =\sqrt{r^2}

\sqrt{144 m^2} =r

12 m= r

The radius of the circle is 12 meters, but the question asks for diameter. The diameter is twice the radius.

d= r*2

The radius is 12 m.

d= 12 m*2

Multiply

d= 24 m

The diameter of the circle is 24 meters.

The required time is 3 years.
AVprozaik [17]

Answer:

Step-by-step explanation:

<h2><em>For 4%</em></h2>

<em>A = $56,363.59 </em>

<em> </em>

<em>A = P + I where </em>

<em>P (principal) = $50,000.00 </em>

<em>I (interest) = $6,363.59</em>

<h2><em>calculation step</em></h2>

<em>First, convert R as a percent to r as a decimal </em>

<em>r = R/100 </em>

<em>r = 4/100 </em>

<em>r = 0.04 rate per year, </em>

<em> </em>

<em>Then solve the equation for A </em>

<em>A = P(1 + r/n)nt </em>

<em>A = 50,000.00(1 + 0.04/12)(12)(3) </em>

<em>A = 50,000.00(1 + 0.003333333)(36) </em>

<em>A = $56,363.59 </em>

<em> </em>

<em>Summary: </em>

<em>The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 4% per year compounded 12 times per year over 3 years is $56,363.59. </em>

<h2><em>for 5 %</em></h2>

<em> </em>

A = $58,073.61

A = P + I where

P (principal) = $50,000.00

I (interest) = $8,073.61

<h2>calculation step</h2>

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 50,000.00(1 + 0.05/12)(12)(3)

A = 50,000.00(1 + 0.004166667)(36)

A = $58,073.61

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 5% per year compounded 12 times per year over 3 years is $58,073.61.

<h2>For 6 %</h2>

A = $59,834.03

A = P + I where

P (principal) = $50,000.00

I (interest) = $9,834.03

<h2>calculation step </h2>

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 50,000.00(1 + 0.06/12)(12)(3)

A = 50,000.00(1 + 0.005)(36)

A = $59,834.03

<h2 />

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 6% per year compounded 12 times per year over 3 years is $59,834.03.

Zielflug [23.3K]
2(2y-10)+3y=1240
7y-20=1240
7y=1260
y=180
2x+3(180)=1240
2x+540=1240
2x=700
x=350
So they sold 350 food tickets and 180 ride tickets in total.
