Solve this problem?

Answer 1

Hiii.....

Circumference of circular garden = 2 ×pie× r = 440 m ...

r = 70 m.....
Area of garden = pie × r^2 = 3.14 × 70^2
= 15400 m sq....

Total area of garden without path ( r = 70 - 7 = 63 ) = pie × r^2 = 3.14 × 63^2
= 12474 m sq.....

Area of path = 15400 - 12474
= 2926 m sq......

Answer 2

hello users .....

solution:-
we know that
Area of circle = πr²
and.
circumference of circle = 2πr

let,
R is the radius of circular garden.
and
r is the radius of circle formed 7m inside the garden.

According to given:
circumference of larger circle (garden)
=> 2πR = 440m
=> πR = 220m
=> R= 220/π
=> R = 220 × 7 / 22 = 70m

now,
Area of circular garden = πR²
= 22/7 × 70²
= 22/7 × 4900
= 22× 700 = 15400 m²

now,
Area of circle formed 7m inside the garden
=> the radius of new circle formed
=> r = 70 -7 = 63 m

Area = πr²
= 22/7 × 63²
= 22/7 × 3969
= 22× 567
= 12474 m²

now.
the area of circular path = Area of circular garden - Area of circle formed 7m inside the garden.

=> 15400 m²- 12474m²
= 2926 m² Answer
