(a) 19.64 (b) 18.64
(c) 17.64
of 720 ice​

Answer 1

Answer:

$19.625 {cm}^{2}$

Step-by-step explanation:

area of circle =

$\pi {r}^{2}$

diameter= 2 r = 5cm

R = 2.5cm

let π = 3.14 (approx)

then...by solving we get...

$19.625 {cm}^{2}$

Answer 2

Answer:

r = 5/2

area of circle =π r2

22/7 (5/2)

= 55/7

=7.85714285714
