The circle below is centered at the point (-1,3) and has a radius of length 4

Snowcat [4.5K]

(x-h)^2 + (y-k)^2 = r^2 where h & k are the x,y values of the center point

(x + 1)^2 + (y-3)^2 = 4^2

The diagram shows a logo made from 3 circles.

Cloud [144]

Answer:

% area of the shaded region = 33%

Step-by-step explanation:

Radius of the middle circle = 7 cm

Radius of the inner circle = 4 cm

Area of the middle circle = πr²

= π(7)²

= 49π

Area of the inner circle = π(4)²

= 16π

Area of the shaded region= 49π - 16π

= 33π

Area of the outermost circle = π(10)²

= 100π

% area of the shaded region = $\frac{\text{Area of the shaded region}}{\text{Area of the inner circle}}\times 100$

= $\frac{33\pi }{100\pi }\times 100$

= 33%

Therefore, area of the shaded region is 33% of the complete logo.
