wlad13 [49]3 years ago
7 0
C = 2pi(r). Find the radius of the circle first. Then multiply that by 2pi. 
Pi=3.14159... 2pi = 2 x 3.14159...
Therefore C = 2 x 3.14159... x r

The diagram shows a logo made from 3 circles. Each circle has a centre 0. daisy says exactly 1/3 of the circle is shaded. is dai
marusya05 [52]

Daisy is not correct. The shaded part is 3/50 that of the whole circle.

<h3>Is Daisy correct?</h3>

In order to determine if Daisy is correct, the area of the circle and the area of the shaded part has to be determined.

Area of the circle = = πr²

Where :

π = pi = 22/7

r = radius = 4 + 3 + 3 = 10

10²π = 100π

Area of the shaded part = 3²π = 9π

Ratio of the areas = 9π / 100π
