Question

12. The diameter of a circle is 2.42m. Calculate its
area in proper significant figure​

Answer 1

A = 4.6 [m²]

Step-by-step explanation:

The area of a circle can be calculated by means of the following equation.

`A=(\pi )/(4) *D^(2)`

where:

A = area [m²]

D = diameter = 2.42 [m]

Now replacing:

`A=(\pi )/(4) *(2.42)^(2) \\A = 4.6 [m^(2) ]`
