Answer:
1 A = πr²
= 3.14 × ( 9.5 × 9.5 )
= 3.14 × 90.25
= 283.385 cm²
2 A = πr²
= 3.14 × ( [ 14 ÷ 2 ] × [ 14 ÷ 2 ] )
= 3.14 × 49
= 153.86 cm²
3 A = πr²
= 3.14 × ( 13 × 13 )
= 3.14 × 169
= 530.66 cm²
4 A = πr²
= 3.14 × ( 11 × 11 )
= 3.14 × 121
= 379.94 cm²
The area of the circular clock is 379.94 cm².
5 A = πr²
= 3.14 × ( [ 15 ÷ 2 ] × [ 15 ÷ 2 ] )
= 3.14 × 56.25
= 176.625 m²
The area of the circular pool is 176.625 m².
