Question

can anyone plz answer this ?

Answer 1

Answer:

Here are your questions solutions

Step-by-step explanation:

1) circumference of circle = 2π r

2 π r = 44

2 x 22 / 7 x r = 44

44 / 7 x r = 44

r = 7 cm

2) area of a circle = π r²

= 22 / 7 x 7²

22/ 7 x 49

= 22 x 7

154 cm²

3) radius = diameter / 2

= 9.8 / 2 = 4.9 cm

now , area of the circular garden = π r²

= 22 / 7 x 4.9 x 4.9

= 75.46cm²

4) area of square = a²

a = 1m = 100 cm

area = (100)² = 10000cm²

5) area of rectangle = Length x Breadth

= 12 x 10 = 120 cm²
