A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

Answers

Answer 1

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Answer 2
3.14(18^2) basically do that

So, the base is always going to be the bottom of our traingle, or any other shape.

The height will be what goes in the vertical direction of the base.

If your base is vertical, like: I , then your height will be horizontal, like: - .

No matter where the base is, the height will be exactly 90 degrees different(since there is a 90 degree difference between vertical and horizonatal)

A small theater sold 36 adult tickets. The ratio of adults to children was 4:3. How
many child tickets were sold?

Answers

Answer:

27

Step-by-step explanation:

if the theater sold 36 adult tickets and the ratio of adult to children was 4:3, we already know that they sold more adult tickets than children tickets. to turn 36 into 4, we divide 36/4 to get 9, 4*9=36 so we have to do this to the 3, 3*9=27. 36:27 is equal to 4:3.

if the ratio of adults to children was 4:3 27 child tickets were sold

What is inequality?

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

1. Top or Bottom

Corners: (2c+100) x 8Non- corners: 10(c+100) x 4 x210 x 10x 100 x 2 =20000

2. Middle Layers:

Corners: (c+100)x 4 x 10Non- Corners: 100 x 10 x 4 x 10 =40000

So,

(2c+100) x 8 + 10(c+100) x 4 x2 +  (c+100)x 4 x 10 + 20000 + 40000

16c + 800 + 80c + 8000 + 40c + 400 + 60000

136c + 72800

As per the condition:

136c + 72800≤ 85000136c≤85000-72800

c≤89

and, 136c≥80000-72800

 c≥53

c= 89-53 =37

Hence, the number of such values of c is 37
