How do you convert the diameter of a circle to square Inches?

If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.


What is the cubic inch. lengthe is 4 inches and the sphere has a diameter of 3 inches.?

A sphere cannot have a length of 4 inches and a diameter of 3 inches. Make sure you know what shape your question is about!


If the diameter of a circle is 20 inches what is the radius of the circle?

10 inches The diameter of a circle is twice the radius, so 1/2 of 20 inches is 10 inches. to make this sound easier: you just take half of the diameter. for instance lets say the diameter was 5. so your thinking: how can you split a odd number in half but you just turn the diameter of 5 and turn the radius into 2.5. u with me?? hoped i helped!! :) :)


How long does a piece of string need to be to make a circle that is 32 inches in diameter?

pi*32 = 100.53 inches (approx)


What is the diameter of circle whose area is 1693.14 in square?

pi*radius2 = 1693.14 square inches Make the radius the subject of the above then double for the diameter diameter = 46.430 inches to 3 decimal places


How many 12 inch long blocks do you need to make a circle of 25 feet?

Circumference of a 25 feet circle = pie x diameter x 12 942.477 inch 1 feet = 12 inch so i converted into inch as i am having the other component in inch No of 12 inch long blocks = circumference /12 so total 78 pieces will be required to make a circle of dia 25 feet


Did they ever make a 2 inch silver coin?

No, the US mint has never minted a 2 inch silver coin for circulation or for bullion purposes. The largest silver coin in diameter that I know of that was produced by the US mint would be the American Silver Eagle with a diameter of about 1.58 inches and the US silver dollars which have a diameter of 1.5 inches.

What happens to the area of a circle if the diameter is doubled?

If you double the diameter of a circle, the area will quadruple (be 4x greater).The area of the circle increases exponentially with the diameter, or more precisely with the radius, which is 1/2 the diameter. A = (pi)r2Doubling the diameter of a circle will quadruple the area (22 =4).This is easily seen in pizzas, where the dough needed for a 16-inch pizza can be used instead to make 4 pizzas with a diameter of 8 inches.---The equation to find the area of a circle is a=(pi)r2. If the diameter is doubled, then the radius is also doubled, because the radius is just half the diameter.The area of a circle once its radius (and therefore diameter) has been doubled can be expressed as follows: a'=(pi)(2r)2, which simplifies to a'=(pi)(4r2).To find the proportion of a' and a, we just divide the second by the first. This gets us[(pi)(4r2)]/[(pi)(r2)]=4


Explain how to do the basic math to determe 3.14 x diameter 2squared?

Your question doesn't make sense. The area of a circle is Pi (approximately 3.14) times the RADIUS squared. An example would be a circle with a diameter of 6 inches and thus the circle would have a radius of 3 inches. Three squared (3 times 3) is 9, and 9 times Pi is approximately 28.3 square inches.


How many radius make a diameter?

A circle's diameter is twice its radius.


What is the exact diameter of a circle?

There is no exact answer it depends on the circle. It is however you make it.
