Answer:
TSA = 175.84 ft²
Step-by-step explanation:
We are given;
Lateral surface area; A_L = 75.36 ft²
Area of base; A_b = 50.24 ft²
Height of cylinder; h = 3ft
Formula for total surface area of Cylinder is;
TSA = 2πr² + 2πrh
Now, lateral surface area is given by the formula; A_L = 2πrh
Area of base is given by the formula;
A_b = πr²
Thus, let's apply these 2 formulas to the formula for total surface area;
TSA = 2(Area of base) + Lateral surface area
TSA = (2 * 50.24) + 75.36
TSA = 175.84 ft²
Answer:
51 gal
Step-by-step explanation:
Find the area of the wall you need to paint:
12 m * 80 m = 960 m^2
Use conversion rate to convert square meters to square feet (first, make the conversion rate into square meters instead of regular meters):
1 ft / 0.3048 m -> 1^2 ft / 0.3048^2 m^2
960 m^2 * (1 ft^2 / 0.3048^2 m^2)
Square meters cancel out, we are left with square feet:
960 * (1 ft^2 / 0.3048^2) = 10333.354 ft^2
Now, find how many gallons of paint by dividing by 200 square feet:
10333.354 ft^2 / 200 =~ 51.66 gal
Round up to the nearest whole number:
51.66 =~ 51 gal
Answer:
18%
Step-by-step explanation:
3.50-2.87=0.67
18% of 3.50 is 0.67
hope this helps :3

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
