Answer 1

Answer:

5.29π meters square

Step-by-step explanation:

circumference = 2πr

given = 4.6π meters

=> 2πr = 4.6π

=> 2r = 4.6

=> r = 4.6/2 = 2.3 meters

now

area = πr^2

=> area = π × (2.3)^2

=> area = π × 5.29

=> area = 5.29π meters square.

Answer 2

$given \: circumference = 4.6\pi \\ 2\pi \: r = 4.6\pi \\ r = \frac{4.6 \: \pi}{2\pi} \\ r = 2.3metres \\ now \: area \: of \: a \: ring = \pi {r}^{2} \\ = 2.3 {}^{2} \times \pi \\ = 5.29\pi \: m {}^{2}$
