Question

(i) The circumference of a circular flower-bed is 88 m. Find its are (ii) The area of a circle is 15400 m². Find its circumference​

Answer 1

Answer:

Step-by-step explanation:

given :

• (i) The circumference of a circular flower-bed is 88 m. Find its are (ii) The area of a circle is 15400 m². Find its circumference

to find :

• Find its circumference

solution :

• Circumference of circular flower bed

• = 2 pir So, 88 m = 2 x (22/7) x r

• => (88×7)/44 = r

• => 14 m = r

• Area of circular flower bed = pi x r² = (22/7): x 14² m² =

• = 22/7 x 14 x 14 m²

• = 44x 14 m²

• = 616 m²

Answer 2

Answer:

circumference of circular flower bed

=2π so,88m

=2×(22/7)×r

88×7/44=r

=14m r

area of circular flower bed

=π×r2

22/7×14×14m2

=44×14

=616m 2
