Question

how to find the area of the circle ?
how to find the circumfence ?

please give me one example also .​

Answer 1

Answer:

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.

Use Pi to find the perimeter of a circle. Pi is the ratio of a circle's circumference to it's diameter. If the diameter is 1, the circumference is pi. For the measurement of the area of a circle, simply multiply the radius squared by Pi, expressed as A = pr2.

Answer 2

Answer:

we find area of circle by formula i.e, pieR^2

exp.-

let a circle with radius (R) 7 cm then what is the area of circle

so we se formula

pieR^2

22/7*7*7

so , area of circle=154 cm^2

also we find circumference by 2pieR

we take above example

formula=2pieR

=2*22/7*7

=44cm
