Question

find the diameter with the given circumference is 55m ​

Answer 1

Step-by-step explanation:

2πr = 55

2×22/7×r =55

44/7r = 55

r = 55×7/44

r = 35/4 cm

then, diameter = 35/4 × 2

= 17.5cm..

Answer 2

Answer:

we know that.........

d = 2r

2pi r = circumference

2 ×22/7 ×r = 55

r = 55×7 /44

r= 35/4 cm

acc.to question

d = 2r = 2× 35/4 = 70/4 = 35/2 cm
