Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi. (4 points) C = 11π;
Iteru [2.4K]

Answer:

C = 22π; A = 121π.

Step-by-step explanation:

To find the circumference of a circle, you do pi times the diameter. That would be 22pi.

To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.

So, C = 22pi; A = 121pi.

Hope this helps!

Given the list of x's and y's what is the constant of proportionality. X- 5, 6, 7, 8, 9 Y- 30, 36, 42, 48, 54
Snezhnost [94]

Answer:

Constant of proportionality(X:Y) = 1:6

Step-by-step explanation:

Given:

X- 5, 6, 7, 8, 9

Y- 30, 36, 42, 48, 54

Find:

Constant of proportionality

Computation:

X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54

X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6

So;

Constant of proportionality(X:Y) = 1:6
