What is the formula to calculate the area of a circle?
*=multiplication symbol /=division symbol r*(r*ㅠ)=r2 ......... radius*(radius*pi)=radius2 ........... radius times the radius times pi equals radius squared HINT HINT HINT an easier way to put this is .......... d*ㅠ/2=n ............. diameter*ㅠ/2=answer .......... diameter times pi divided by two equals the answer
What is the area of the circumference of a circle with diameter 7 yd?
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
What is the area of a circle if the radius is 7 mm?
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).
How do you find the area of an oval?
well, an oval is a curved shape like the circle, so we use the same basic principle of πr² (or pi multiplied by (radius squared)). however, unlike the circle, the oval as two differing radii (plural of radius!) so we have to take that into account and adjust our formula accordingly. so the formula instead of squaring one radius, we measure both radii (horizontal radius * vertical radius) an then we multiply that by pi. the simple form of the formula is: π*(r1*r2) r1= horizontal radius r2= vertical radius π is the symbol for pi hope that helps!
What is the area of a circle that has a radius of 3 miles?
Area of a circle formula: pi*radius^2 (pi multipled by (radius squared)) Pi is a number with an infinite number of decimal places, it is on most good calculators (the symbol looks a bit like a bridge, or something from Stone Henge). If you can't find the function for pi on your calculator, use the approximation pi=3.14159. So, Area=3.14159 multiplied by 3^2.
How does a radius symbol look like?
The radius symbol is R. You could use this in: Radius = πr²

How do you fing the circumference if you have the radius?
you have to use the formula : C= 2* radius* Pie symbol. * IS MULTIPLYING. Pie always equals to 3.14, so suppose the radius is 5. You would multiply 5*2*3.14. Your answer would be 31.4.The reason you have to multiply the radius by 2 is because you have to make the radius turn into the diameter which is double the radius to make the equation simpler. Always remember to use pie as 3.14.
How do you find the radius of a circle when the area is known?
First divide the area by pi which you either get by using the pi symbol on a calculator, or by using 3.14159265. Then take the square root of the answer you get from the first step and this is your radius.
What is the area of a circle if the radius is 7 mm?
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).
What is the atomic radius of holmium?
The atomic radius of holmium is approximately 176 picometers. It is a rare-earth element with the symbol Ho and atomic number 67.
Give The formula for radius of curvature in polar form?
The radius of curvature is given by(1)where is the curvature. At a given point on a curve, is the radius of the osculating circle. The symbol is sometimes used instead of to denote the radius of curvature (e.g., Lawrence 1972, p. 4).Let and be given parametrically by(2) (3)then(4)where and . Similarly, if the curve is written in the form , then the radius of curvature is given by
What is the radius of a cylinder when you have the voulme and the height?
volume of cylinder = 'pi'. (radius)2.height V = pi.r2.h Note : pi is a constant, value (approx) = 3.1415....... the dot symbol is the multiplication.. to find radius, rearrange the formula for the value of 'r' i hope this helps BY- Narendra Paudel
Which element has the largest atomic radius?
Francium has the largest atomic radius among the elements.
What has an atomic radius of 099?
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
