Brock has 12 colored pencils, two each of red, green, blue, pink, purple, and black. He wants to determine the probability of taking out two green pencils.
Which of the following would be the most appropriate sampling technique?
OA. He could observe the number of green pencils in one pack of pencils.
ОВ.
He could spin a spinner with four of the six colors represented.
OC. He could roll two six-sided cubes.
OD. He could draw a bar graph.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
