Question

Solve for A if pi-symbol=3.14 and r=3 A=PIrSquared so what is the answer?

Answer 1

The solution for Area, A is 28.26 square units, if pi-symbol=3.14 and radius r = 3, A=PIrSquared.

Explanation:

The given is,

pi -
`\pi` = 3.14

r = 3

A = PIrSquared...................................(1)

Step:1

Formula for area of circle is,

`Area, a = \pi r^(2)`......................................(2)

Equation (1) and Equation (2) both are same, it is used to calculate area of circle.

From given,

radius, r = 3

Substitute the value of radius in equation,

=
`\pi (3^(2))`

=
`\pi` × 9

= 3.14 × 9 (∵
`\pi` =3.14)

= 28.26

Area, a = 28.26 square units

Result:

The solution for Area, A is 28.26 square units, if pi-symbol=3.14 and radius r = 3, A=PIrSquared.
