1
(iii) 55 cm
​

Answer 1

Answer:

diameter= c / π

d = 55m × 7 /22

d = 17.5

Answer 2

$\huge\purple{Required \: Answer :}$

Diameter = 35 cm

$\huge\red{Explanation :}$

Given :

Circumference - 55 cm

To Find :

Diameter - ?

Formula :

$2\pi r$

Solution :

Circumference = $2\pi r$

$55 \: cm = 2\pi r \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: 55 \: cm = 2 \times \frac{22}{7} \times r \\ r = \frac{55 \times 7}{22 \times 2} \\ r = \frac{5 \times 7}{2 \times 2} \\ r = \frac{35}{4} \: \: \: \: \: \\ r = 8.75 \: cm$

Diameter = 2 × Radius

$= 2 \times 17.5 \\ = 35 \: cm \: \: \: \:$

Therefore,

Diameter = 35 cm
