If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).

The circumference of a circle with a 28 unit diameter is: 88cir=dx22/7

Circumference of circle: 28 times pi inches

Circumference of the circle: 28*pi inches

Circumference = pi*diameter = 87.96 inches.

It is: pi*28 meters

Multiply the diameter by pi, which is about 3.14.

d = 8.9 feet

You divide the diameter by two to get the radius (28 / 2 = 14)

28 x 3.1416: circumference is pi times the diameter.

Circumference=2diameter(pi) C=2(28)(pi) C=175.92918860102842135390802946365

A circle with a diameter of 28 is a circle.

It depends on what is meant by 28 yards: diameter? circumference?

The area of a 28-foot diameter circle is: 615.752 feet2If the circumference is 28 feet then the area is 62.388 feet2

If you mean a circle with a diameter of 28 cm, the circumference is 87.96459430051421067695392... using pi to 23 decimal places.* * * * *The answer above implies that the diameter of the circle was measure to an accuracy of 23 decimal places. Very unlikely, I suggest!

Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared

Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.

Perimeter (or circumference) of a circle = pi x diameter = pi x 28, but we need the circumference of only half of it (semicircle is half of a circle) Hence the answer is pi x 14 = 3.1415 x 14 = 43.981 mm

The diameter of a 28-square inch circle is: 5.971 inches.

If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).

The circumference is 175.92918860102841 feet.

The circumference is 18.76 meters.

28"

first we find the circumference which is 2 pi r.then we divide it with half because we want half of circumference,my ans is 72 cm. peri meter is circumference divided by 2 then add diameter in ans

Divide the circumference by pi.
