For questions 1 – 6, find the area of the circle to the nearest hundredth.<br> Any help appriciated!
Ganezh [65]

Step-by-step explanation:

The area of a circle is given by :

A = πr²

r is the radius of the circle

(4) Diameter = 22 cm

Since, radius = diameter/2

r = 11 cm

Now, area of the circle,

A=\pi \times (11)^2\\\\A=380.13\ cm^2

(5) Diameter = 30 cm

Since, radius = diameter/2

r = 15 cm

Now, area of the circle,

A=\pi \times (15)^2\\\\A=706.85\ cm^2

(6) Diameter = 4cm

Since, radius = diameter/2

r = 2 cm

Now, area of the circle,

A=\pi \times (2)^2\\\\A=12.56\ cm^2

So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
