Find the area of the figure give below in m².

A: 295 .7114 cm²

B: 2.957m²

C: 0.02957m²

D: 0.2957m²

Correct Answer : C

i) One way you can convert the radius to m first and then calculate the area of the circle

100cm = 1m 

9.7 cm = ?
(9.7 x1)/100 = 0.097m

Area = πr²
A = (22/7) ×  0.097²
A = 0.02957m²

i) Another way is to calculate the area in cm² and convert its area to m²

Area = πr²

A =  (22/7) × 9.7²
A = 295 .7114 cm²


convert the area to m²
1m² = 10000 cm²
? = 295 .7114 cm²
( 295 .7114 * 1 ) / 10000
A = 0.02957m²
