The formula for circumference is
c = pi*diameter
and the formula for area is
a = pi*r^2
Therefore, the circumference is 9.3*pi
and the area is pi*(4.65)^2
*4.65 since the radius is half the diameter*
*You could substitute pi with 3.14, though leaving your answers in terms of pi is better*

How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What is the area and circumference of a circle with a diameter of 8.5MM?
Circumference: multiply the diameter by pi (approximately 3.1416). Area: Divide the diameter by 2 to get the radius. Then use the formula area = pi x r2, where r is the radius.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)

What is the area and circumference of a circle with diameter 55 centimeters?
what is the area and circumference of a circle with a diameter of 55 centimeters
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
What is the diameter of the base of mount Etna?
The base has a circumference of 93 miles
What is the area of a 93-inch circle?
If you mean a circle with a 93 inch diameter - it will have a 46.5 inch radius, giving it an area of ~6792.909 sq inches = ~47.173 sq ft. If you mean a circle with a 93 inch circumference - that will have a diameter of ~29.6 inches (radius of ~19.8 inches) and an area of ~688.3 sq inches = ~4.78 sq ft.
What is the diameter radius circumference and area of a circle with a diameter of 6?
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Square foot of a circle?
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
If 7 is your radius and 14 is your diameter then what is the circumference and area answer?
Circumference is about: 44 Area is about: 153.94
How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
