Step-by-step explanation:

pi * r^2 = area

The radius = diameter/2 = 6

The ordered pair below is a solution to which equation?. . (3, 15). . A. y = 5x. B. y = 3x. C. y = 1/5x. D. y = 1/3x
Lelechka [254]
The solution to the ordered pair (3,15) is the equation y = 5x, which is letter A. This is found by substituting the value of the x into the equation and solving for y. The equation y = 5x satisfies the ordered pair (3,15) because if you substitute x with 3, the equation becomes y = 5(3) which is 15.

50 points: Find the probability that a randomly selected point within the circle falls in the red shaded area..
luda_lava [24]

The probability will be 0.32

Step-by-step explanation:

Find the area of the shaded region

Area of a triangle is given by = 1/2 product of base and height of the triangle

Area of a triangle= 1/2*b*h where b is base length and h is height of the triangle

A=1/2*4*4 *2 =16 cm²

Area of the circle = π×r² where r is radius=4 cm and π =3.14

Area of the circle= π × 4×4 =16π =50.24 cm²

The probability that a randomly selected point within the circle falls in the red shaded area will be : P(area of shaded part/area of circle)

p=16/50.24 =0.31847133758

p=0.32 (rounded to the nearest hundredth)
