Probability of landing in the white not the red. Please helpppppppppppp!

Iteru [2.4K]

Fun, geometry disguised as probability.

That's a pentagon, which we can view as 10 right triangles with legs a and s/2 (half of s) and hypotenuse r. So area of the pentagon is

P = 10 × (1/2) a (s/2) = 10 (1/2) (3.2) (4.7/2) = 37.6

The area of the circle is πr² so the circle area is

C = π (4²) = 50.265482

The white area is the difference, C-P, and the probability we seek is the fraction of the circle that's white, so (C-P)/C.

p = (C-P)/C =1-P/C = 1-37.6/50.265482 = 0.251971

Answer: 0.25

Higher than I would have guessed from the figure.

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.
