(c) the area of the lawn excluding the area of the flowerbed.
(d) the circumference of the flowerbed.​

Answer 1

Answer:

1 )

${50m}^{2}$

2 )

${12.56m}^{2}$

3 )

${37.44m}^{2}$

4 )

12.56m

Answer 2

Answer:

( a ) 10 × 5 = 50m²

( b ) = π × 2² = 3.1417 × 4

= 12.56m²

( c ) = 50m² - 12.56m²

= 37.44m²

( d ) circumference of circle = 2πr

= 2 × π × 2m

= 4 × πm

= 12.56m
