The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 .

: Plug in the value we just found for r.
3.

: Use the order of operations (PEMDAS).
4.

The area of the circle is equal to
20 liters. If there’s 8 liters every 2 days, 8 divided by 2 is 4. 4x5 is 20 liters.
Answer:
$1.60
Step-by-step explanation:
So, to find the persent of a number, we need to make the percent a decimal.
So, 20% is equal to 0.2
Then, we need to multiply 0.2*8
8.0
* 0.2
________
1.6
So, our answer is 1 dollar and 60 cents!
45 because 1-4 round down and 6-9 round up to make the 44 become a 50
Answer:
When the ticket price is $3 or $4 the production will be in break even
Step-by-step explanation:
<u><em>The correct question is</em></u>
The revenue function for a production by a theatre group is R(t) = -50t^2 + 300t where t is the ticket price in dollars. The cost function for the production is C(t) = 600-50t. Determine the ticket price that will allow the production to break even
we know that
Break even is when the profit is equal to zero
That means
The cost is equal to the revenue
we have


Equate the cost and the revenue

solve for t


Solve the quadratic equation by graphing
using a graphing tool
the solution is t=3 and t=4
see the attached figure
therefore
When the ticket price is $3 or $4 the production will be in break even
