(ii) diameter is 42 cm​

Answer 1

Answer:

219.91 is the answer of 1 questions

Answer 2

Answer:

(i) 220, (ii) 132

Explanation:

Circumference of a circle is

$2\pi \times r$

Therefore

$2\times \frac{22}{7} \times35 = 220$

And

Radius of a circle is half of diameter

Therefore,

$2 \times \frac{22}{7} \times \frac{42}{2} = 132$
