Step-by-step explanation:

2

$2 \: \pi \: r \: l$

$2 \times \frac{22}{7} \times 3.5 \times 10 \\ = \frac{1540}{7} \\ tsa= 220 \\ it \: took \: 300 \: revolutions \: \\ so \: \\ = 220 \times 300 \\ = 66000$

Answer 2

Step-by-step explanation:

SOLUTION :-

$† Circumference = 2πr²$

$→ 2 \times \frac{22}{7} \times 3.5 × 10$

$→ \frac{1540}{7}$

TSA = 220

It took 300 revolution,

$→ 220 \times 300$

$→ Answer = 66000$

ANSWER :- 66,000
