What is the area of a circle whose diameter is 75mm?

A=πr2Plug in the radius. Do the math.


75mm equals how many cm?

75mm = 7.5cm


What is area of semicircle?

The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.


What happens to the area of a circle when the radius is doubled tripled?

The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.


What is a radius square?

When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.


What happen to the area of circle when the radius is tripled?

If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.


If the radius of a circle decreased would the area decrease?

Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.


What is the area of a regular pentagon with a radius of 7?

The area of a regular pentagon with a radius of 7 is 10.1716. If the radius was 5, the area would be 7.26543.


Formula for finding volume and area of sphere?

Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius


What is the radius of circle with an area of 110?

Use the formula for the area of a circle (area = pi x radius squared), replace what you know (in this case the area), and replace - in this case - for the radius.


What is the radius of a circle that has an area of 6644.24?

As area = pi * radius2, the radius is given by radius = sqrt(area /pi) radius = sqrt(6644.24 / pi) = 46 with pi = 3.14


What is a java code for calculating area of a circle?

area = radius * radius * Math.pi;


What is the area of circle with a radius of 35?

Area of a circle = pi*radius squared


What is the area of a circle with a radius of 3'-6?

Area = pi*radius squared

The area of a circle of radius 21 is 1386


If radius of a circle is diminished by 10 percent then it's area is diminished by?

Radius 10, area = 100 pi; radius 9, area = 81 pi


How do you find the area of a circle that has a diameter of 4. 2?

2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86


Is the radius of a circle a function of its area?

You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)


What is the area of a circle of the radius of 10m?

A circle with a radius of 10m has an area of 314.16 m2


What ios the formula for the area of a radius?

A radius is a line segment. It has no area.


How do you find the radius of a circle if you only know the area?

Radius = +sqrt(Area/pi)


Is the area of a circle is twice the radius?

Area equals pi times the radius squared.


What is the relationship between the area and the radius?

In relation to the area of a circle: pi*radius^2


The area to an 80 mile radius?

The area of a circle is: pi times radius^2


How do you find the diametre if you have the area?

Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
