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)
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)
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
If area of a circle is tripled what haappens to the circumference?
The formula for the area of a circle is, A = πr2 If the area is tripled then the larger circle has an area of A2 = πR2 (where R is the new radius) But, πR2 = 3πr2 : R2 = 3r2 : R = r√3 The circumference of the original circle was 2πr. The circumference of the larger circle is 2πR = 2πr√3 Therefore, if the area is tripled, then the circumference increases by √3.
Write a shell program to find the area and circumference of the circle?
echo -n "Enter the radius of a circle : "read r# use formula to get itarea=$(echo "scale=2;3.14 * ($r * $r)" | bc)# use formula to get itd=$(echo "scale=2;2 * $r"|bc)circumference=$(echo "scale=2;3.14 * $d"| bc)echo "Area of circle is $area"echo "Circumference of circle is $circumference"# ### softspy88@gmail.com
What is the formula of finding the circumference of a sphere?
4*pi*r2. because surface area is equal to circumference of circle.
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
What is the Formula of circumference and area of a circle?
The formula for the circumference of a circle is: radius (x) 3.14 (pi) Area is... Radius2 x 3.14
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
What is the formula for area and circumference of a circle?
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
What is the circumference of a circle is 22 units what is the area?
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
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)
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)
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
