Question

Calculate the area of a circular disc 5.86 cm in diameter​

Answer 1

26.97 cm^2 to nearest hundredth.

Explanation:

Radius = 1/2 diameter

= 2.93 cm

Area = π r^2

= 2.93^2 π

= 26.97 cm^2

Answer 2

27 cm^2

Explanation:

Area of a circle = pi r^2

you are given diameter = 5.86 so radius = 2.93cm

Area = pi * (2.93)^2 = 26.97 =~ 27 cm^2
