Question

find the area of circle diameter = 2.8cm and also find perimeter of circle. ​

Answer 1

Step-by-step explanation:

diameter = 2.8 ,

then, radius (r) = 2.8÷2 = 1.4

since Area of circle = πr^2

=( 22/7)× (1.4)^2

= (22× 1.4 × 1.4)/ 7

= 6.16 cm^2 Answer

since perimeter of circle = 2πr

= 2×( 22/7 )× 1.4

=8.8 cm Answer

hopefully , It 'll be helpful for u !

Answer 2

• Perimeter = 8.8
• Area = 6.16

Step-by-step explanation:

Radius - 2.8/ 2

To find perimeter first

Circumference of circle - 2πr

=2* 22/7 * 1.4

= 8.8 cm

To find area

Area of circle - πr sq.

= 22/7 * 1.4 * 1.4

=6.16 cm sq.
