What is the base area of a cylinder with a radius of 2
Alex17521 [72]

Answer:

(pi)4 or about 12.57 sq. units

Step-by-step explanation:

The base area of a cylinder is a circle.

Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.

So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)

You and your friend are selling tickets to a charity event. you sell 12 adult tickets and 6 student tickets for $138. your frien
mr Goodwill [35]
Let's say the cost of student tickets is x and the cost of adult tickets is y. Then:

(1) 12y + 6x = 138
(2) 5y + 11x = 100

If we rearrange equation (1) we get:
12y = 138 - 6x
Now divide each side by 12:
y = 11.5 - 0.5x

We can now substitute this into equation (2):

5(11.5 - 0.5x) + 11x = 100
57.5 - 2.5x + 11x = 100
8.5x = 42.5
x = 5, therefor the cost of a student ticket is $5.00
