Question

find the area of a circle of radius 30 cm( use π = 3.14).​

Answer 1

Answer:

Area of the given circle (A)

Area of the given circle (A)= 2826 cm²

Step-by-step explanation:

Given,

radius of a circle (r)=30 cm

and

π = 3.14

/* we know the,

*/

Now ,

A = 3.14 ×(30 cm)²

=> A = 3.14 × 900 cm²

=> A = 2826 cm²

Therefore,

Area of the given circle (A)

= 2826 cm²
