Question

Radius of circle is 4.9cm then it's area is in cm

Answer 1

Answer:

Area=75.46 $cm^{2}$

Step-by-step explanation:

area of circle =$\pi r^{2}$

here r=4.9

(4.9)(4.9)( 22/ 7 )

=24.01( 22/ 7 )

=75.46$cm^{2}$

Answer 2

Answer:

Area of the circle = πr²

so for a cirle with radius 4.9cm the area would be.. π×(4.9) ²

= 3.14×24.01

approx.. = 75
