What is the formula of finding the area of a circle?
Pi * R squared, where R is the radius of the circle in question
Why does the formula for area of a circle work?
It says so in the formula
Find the area of each what A circle of radius 3cm A rectangle that has a length of 14 inches and a width of 2 inches A triangle with a base of 0.4 feet and a height of 0.7 feet?
1. The formula for finding the Area of a circle is Pie X R-squared. R 3 cm squared is 9cm X 3,14 (value of Pie) = 28.26 square inches. 2. The formula for finding the Area of a rectangle is Length X Width (LXW): 14 X 2 = 28 square inches. 3.The answer is...900 ins. are in 75 ft. 24
Why does x equal 0 when finding the sin of 90 degrees?
On the unit circle sin(90) degrees is at Y = 1 and as that is on the Y axis X will equal = 0. Ask yourself. Where would 90 degrees be on a 360 degree circle? Straight up.
Is a circle graph a function?
No, a circle graph is never a function.
How do you get the radius from the circumference?
The circumferance of a circle is equal to 2 x pi x r, where r is the radius, i.e. approximately 6.2832 than its radius. Divide the circumferance from the figure above to get the radius of a circle in which the circumferance is known.
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the circumferance of 10m dia circle?
It is: 10*pi
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
What is formula ofr finding area of a circle?
Area of a circle = pi*radius squared
What is the circumference of a semi circle with a six inch radius?
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the formula of finding the area of a circle?
Pi * R squared, where R is the radius of the circle in question
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is the circumferance of a seven eighths inch circle?
7/8 inch circle has a diameter of 7/8 and a radius of 7/16=.4375 circumferance of a circle = 2*pi*radius = 2*3.14*.4375 =2.7475 or 7*pi/8
What formula is pi d?
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
