Answer:

2 : 2.5

Step-by-step explanation:

4 : 5 ----> 4x, 5x

4x + 5x = 4.5

9x = 4.5

x = 4.5 / 9

x = 0.5

4x

= 4 x 0.5

= 2

5x

= 5 x 0.5

= 2.5

4 : 5

= 4x : 5x

= 2 : 2.5

Find the area of a circle that has a diameter of 11 inches. Approximate Π as 3.14. Round your answer to the nearest hundredth.
Alexus [3.1K]

Answer: 94.99 in^2

Step-by-step explanation: The equation for the area of a circle is A=πr^2. To solve this, we need to find the radius. The diameter is the whole circle, whole the radius is half. So divide the diameter by 2.

11/2 = 5.5

The radius is 5.5 inches. Plug the radius into the equation.

A=π5.5^2

Square the 5.5 first. You will get 30.25.

A=π30.25

Plug in 3.14 for pi.

A=3.14 x 30.25

Multiply.

A=94.985

Round to the nearest hundredth.

A=94.99

The area of the circle is 94.99 in^2.
