Question

Plz solve it stepwise in the paper plz bro I will give you 25 point but plz solve in the paper fast because it's urgent

Answer 1

1 ). the ratio of their circumference is 2:5 only
Since. 2πr1 /2πr2 = r1/r2
2) 2πr = 44
Therefore r=7
Then area = πr sq. = 22/7 *7*7 = 154 cm sq.
3) πr² = 616
r² = 28*7
r² = 196
r = ±14
Therefore r = 14

Answer 2
