The circumference of the circle is 88 inches, and the area is 616 square inches.
Here, we have,
To find the circumference and area of a circle, we can use the formulas:
Circumference = π × Diameter
Area = π × (Radius)²
Given that the diameter of the circle is 28 inches, we can calculate the radius by dividing the diameter by 2:
Radius = Diameter / 2
= 28 inches / 2
= 14 inches
Using the value of π as 22/7, we can now calculate the circumference and area:
Circumference = π × Diameter
= (22/7) × 28 inches
= 88 inches
Area = π × (Radius)²
= (22/7) × (14 inches)²
= 616 square inches
Therefore, the circumference of the circle is 88 inches, and the area is 616 square inches.

Radius is 14
14 * 22/7 = 44
The area is 44
C=2πr
C = 2*22/7*14
The circumference is 88
B. 8/11
C.11/8
D.16/6

4a + 1v =57
-2a +1v= 9
I will multiply the second by -1 to cancel v variable (elimination method)
4a +1v =57
2a -1v = - 9
add both
6a. = 48
a= 8
4a= 32
32 + v = 57
v= 25
32+25 = 57
-16 +25=9
running at the same rate?
We want to create a proportion with minutes over miles for each person. The proportion for this problem is shown below.
30 minutes / 4 miles = 56 minutes / 7 miles
To find out if these people are running at the same rate, we can cross-multiply.
224 = 210
Because 224 and 210 are not equivalent, the people are not running at the same rate.
Hope this helps!! :)
