A circular lawn of radius 10 mhas a circular flower bed of radius 5m dug into it.
What is the area of the remaining lawn? Give your answer in terms of pi (3.14)

75π  ≈  235.62

Step-by-step explanation:

R represents the radius of the lawn

r represents the area of the circular bed

So,

Area of the remaining lawn, A = area of the lawn - area of the circular flower bed

A = πR^2 - π^2

A = π(R^2 - r^2)

A = π(10^2 - 5^2)

A = π( 100 - 25)

A = 75π    ≈   235.62

x = 3 ± √(5+y)

hm let me think hm think think hm think yes
