The area ( A ) of a circle can be expressed in terms of pi (( \pi )) using the formula ( A = \pi r^2 ), where ( r ) is the radius of the circle. The circumference ( C ) of a circle is given by the formula ( C = 2\pi r ). Both formulas highlight the fundamental role of ( \pi ) in relating the dimensions of a circle to its geometric properties.

How do you put something in terms of pi?
To express a quantity in terms of pi, you need to relate it to a circular measurement, such as the circumference or area of a circle. For example, if you have the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius, to express the circumference as a multiple of pi. Similarly, for the area, use ( A = \pi r^2 ) to express the area in terms of pi. Simply factor out pi from the equation to achieve the desired expression.
What is the circumference and area of a circle with a diameter of 17 mm?
Circumference in terms of PI = 17 PI Circumference with 3.14 = 53.58 Area in terms of PI is 72.25 Area with 3.14 is 226.86500
What would you multiply the circumference of a circle by if you want to find the area of the circle?
To find the area of a circle, you would multiply the circumference by the radius and then divide by 2π (since the circumference (C) is (2πr) and the area (A) is (πr^2)). This means you can express the area in terms of the circumference as (A = \frac{C \cdot r}{2π}). However, it's simpler to directly use the formula (A = πr^2). Thus, you wouldn't multiply the circumference by a single number to find the area; instead, you would need the radius.

What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.

Circumference in terms of pi = 2pi yards Area in terms of pi = pi square yards
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
How do you find the area of a circle when you already know the circumference?
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
How do you express the area of a circle as a function of its circumference?
By using the well-known formula, A = pi x r2, and expressing the radius in terms of the circumference, r = c / (2 x pi). Replace in the first formula, and simplify. f
