SVEN [57.7K]

The formula of an area of a circle:

A_O=\pi r^2

We have

r = 1.8 m

π ≈ 3.14

Substitute:

A_O=\pi\cdot1.8^2=3.24\pi\ m^2\approx3.24\cdot3.14=10.1736\ m^2\approx10.17\ m^2

If f(x) = 10 + 50x, solve for x when f(x) = 310.
weqwewe [10]

x = 6

given f(x) = 310, we obtain the equation

10 + 50x = 310 ( subtract 10 from both sides )

50x = 300 ( divide both sides by 50 )

x = \frac{300}{50} = 6

Suppose that all the points on the circular dartboard shown are equally likely to be hit by a dart. if the radius of the red cir
Anestetic [448]
This equals the  the area of white part / area of the entire dartboard

area of the entire board = pi * 6^2 = 36pi

area of white part = 36pi  - 2^2*pi  = 32pi

do required probability = 32pi / 36pi  =  0.889   or 88.9 %   (to nearest tenth)


or as a fraction it is 8/9
