getcalc.com's Circle Calculator is an online basic geometry tool to to find the area, circumference, diameter or radius of a circle, in both US customary and metric (SI) units.
Steps to Find Area of a Circle
The step by step workout for how to find what is the area of a circle. Students may use this circle calculator to generate work with steps for any other similar input values.Workout :
step1 Address the formula, input parameters and values
Radius = 5 in
step 2 Find area of circle using radius values
Area = πr²
= π x (5)² in²
= 22/7 x 25 in²
Area = 78.5714 in²
Circle and Formulas
Circle is a round plane with every point on its boundary consists of equal length from the center point. Any distance between any point on the boundary and the center is called the radius. The straight from any point to another through the the center point is called the diameter. K-12 students may refer the below formulas of circle to know what are all the input parameters are being used to find the area, perimeter or radius of a circle.
