The circumference of the circle is about 339 cm.

The area of the circle is about 9, 156 cm∧ 2

NOTE :

The circumference of a circle is known to be the perimeter of the circle.

It is determined using ;

Circumference, C = 2 π r

The area of a circle is known to be the axis occupied by the circle in a two-dimensional plane.

It is determined using ;

Area, A = π r ∧2

How to determine the area and circumference of a circle

Parameters:

π = 3.14

radius, r =54 cm

Circumference, C = 2 π r = 2 × 3.14 × 54 = 339. 12 cm

Circumference , C in the nearest hundredth = 339 cm

Area, A = π r∧ 2 = 3. 14 × 54 × 54 = 9,156.24 cm∧ 2

Area, A in the nearest hundredth = 9,156 cm∧2

Thus, the circumference of the circle in the nearest hundredth is 339cm and the area of the circle in the nearest hundredth is 9, 156 cm∧2
