In the formula for the area of a circle what's gets multiplied?
Algebraically, it is ; - A = pi r^(2) In words, it is ' Area equals 'pi' multiplied to the radius squared'. NB 'pi' is a constant at 3.141592..... usually shortened to '3.14'. The radius (r) is the distance from the circle centre to the circumference/edge. 'radius squared' is r^(2) , that is 'r' multiplied to 'r' ; r X r = r^(2) . NNB The circumference of a circle is ; C = 2 pi r Note the power/exponent of '2' becomes a coefficient. In words ' Circumference equals two multiplied to 'pi' multiplied to the radius. (NOT radius squared).
How do you calculate the volume of concrete in a circular slab?
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
How do you find the area circumfrance and the diameter of a circle?
Formula for area: A = Pi*R² (Pi = 3,1416 and R² is the radius multiplied by itself) Formula for circumference: C + Pi*D (D is diameter) Formula for Diameter: D = 2*R (radius multiplied by 2))
What is the equation for determining radius of a circle if you have the circumference?
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
What is the diameter of a circle if the circumference is 7?
divide dy pi. the rule is diiameter (or 2 radius) multiplied by pi equals circumference so: 2 pi x radius= circ and, since diameter is 2 times the radius, pi x D= circ
Why is pi used to find the circumference of a a circle?
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
How do you volume of a cone?
1/3 multiplied by pi multiplied by radius squared multiplied by height
What is pi multiplied by 4?
The answer is 12.56
What is 142980 multiplied by pi?
449184.53
What is the circumference of a circle that has a radius of 3.9?
24.492, unless you want more digits of pi besides the standard 3.14. The circumference of a circle is equal to the diameter multiplied by pi, or the radius multiplied by two, then multiplied by pi. c = d*pi c = 2*r*pi c = circumference d = diameter r = radius pi = 3.141593
What is formula for volume of cylinder?
pi multiplied by r squared multiplied by height
Given a sphere with radius r what does the formula represent?
Do you mean volume or surface area? volume = 4/3 x pi x r^3 (four divided by three, multiplied by pi, multiplied by radius cubed). surface area = 4 x pi x r^2 (four multiplied by pi, multiplied by radius squared).
What is pi multiplied by e?
8.53973 (rounded)
What is 8 multiplied by pi?
25.12 dah
What is the base are of a cylinder?
Pi multiplied by the Diameter.
Is there a number when multiplied by pi equals a number without decimals?
Yes. 1/pi. pi x 1/pi = 1.
Is a number multiplied by pi irrational?
Maybe. It depends on the number that you are multiplying. Pi multiplied by (1 / 4pi) = 1/4. A quarter is definitely rational.
