Area of a circle is πr^2.

The radius of the smaller circle with diameter 10 cm is 5 cm.

The radius of the larger circle with diameter 20 cm.is 10 cm.

Area of larger circle : Area of smaller circle

Area of larger circle = 100π.

Area of smaller circle = 25π.

Ratio = 100π : 25π or 100π/25π.

LiRa [457]

Answer:

A = 907.46 $m^{2}$

Step-by-step explanation:

C = πd

34π = πd

d = 34

r = 17

A = $\pi r^{2}$ = 3.14( $17^{2}$ ) = 3.14(289) = 907.46 $m^{2}$
