Question

22. What is the perimeter and area of a circle with diameter equal to 5 cm​

Answer 1

Answer:

diameter is 5cm

so radius is 5/2cm

perimeter is 2π.5/2cm=2×3.14×5/2cm

=15.70 cm

area of the circle is π.(5/2)^2sqcm

=3.14×25/4sqcm= 19.625sqcm

Answer 2

Perimeter = 12.56 & Area = 47.73

Step-by-step explanation:

perimeter of a circle = 2pieR

Here, Diameter= 5,

Then, Radius = Diameter/2

so, R = 5/2= 2.5

And Perimeter = 2 × 22/7 × 2.5 = 12.56

Area = pie R square

= 47. 73
