Answer 1

Answer:

see the correct answer

Answer 2

SOLUTION:-

Given:

Diameter= 49

So,

⚫Radius= d/2

=) 49/2

Now,

Circumference of the circle:

=) πd

$= > \frac{22}{7} \times 49 \\ \\ = > 22 \times 7 \\ \\ = > 154cm$

&

Area of the circle:

=) πr²

$= > \frac{22}{7} \times \frac{49}{2} \times \frac{49}{2} \\ \\ = > 11 \times \frac{343}{2} \\ \\ = > \frac{3773}{2} \\ \\ = > 1886.5 {cm}^{2}$

Hope it helps ☺️
