What is the area of a circle is 49 circumference what is the radius?
Using 3.14 as Pi the area of circle is: 7539.14
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
What is the circumference and area when radius 9in and d 7.3?
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2
What is the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
How can kids remember the formula for circle area and the formula for circle circumference?
Any formula involving a circle will have "pi" in it. Area = pi* radius * radius Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius) Quick way: A = pi r squared C = pi D
What is the area of a circle if the radius is 7 m?
Using 3.14 as Pi the area of circle is: 153.86
What is the area of a circle is 49 circumference what is the radius?
Using 3.14 as Pi the area of circle is: 7539.14
What is the diameter of a circle with the area 49 pi?
Since the area of a circle is pi times the radius squared. The radius is 7. The diameter would be 14.
What is the area of a circle with a radius of 7 in?
The equation to find the area of a circle is pi x r2, let us just keep pi as pi, if the radius is 7, 72 is 49, so in terms of pi, the answer would be 49 pi, then one would just multiply 49 to whatever digit of pi you wanted to. answer is 153.86 :)
Find the area of a circle that has a radius of 7 inches?
A = (pi) * r^2 = (pi) * (7)^2 = 49*(pi)
What is the area of a circle whose radius is 7?
pi times 49, or if you round pi to 3.14 it's 153.86
What is the circumference and area of a circle with a radius of 7 mi?
Circumference: 14*pi mi Area: 49*pi square mi
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
What is the approximate area of a circle with a radius of 7?
In a circle the area is A=pi*r2 so: A=pi*72 = pi*49 = 153.9380 So, an approximate value would be 153.94 square units
