Answer:
V= 904.896cm^3
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
h - 18cm
d - 8cm
d = 2 * radius
r = d/2
r = 8/2
r = 4cm
π - 3.142
Insert the values into the formula of volume of a cylinder
V = πr^2h
V = 3.142 * 4^2 * 18
= 3.142 * 16 * 18
= 904.896cm^3
Answer:
A) 20%.
B) 26.66%.
C) 40%.
Step-by-step explanation:
Since at the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music, and of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical, to determine the empirical probability that the next person entering the store favors (a) rock music, (b) country music, and (c) something other then rock, country, or classical music, the following calculation must be performed:
A)
60 = 100
12 = X
12 x 100/60 = X
1200/60 = X
20 = X
Therefore, the probability that the next person favors rock music is 20%.
B)
60 = 100
16 = X
16 x 100/60 = X
1600/60 = X
26.66 = X
Therefore, the probability that the next person favors country music is 26.66%.
C)
60 = 100
24 = X
24 x 100 / 60 = X
2400 / 60 = X
40 = X
Therefore, the probability that the next person favors another type of music is 40%.
Based on the properties of a kite, the statement that is true is: D. KPE = TPE.
<h3>What is a Kite?</h3>
A kite is a quadrilateral in which its diagonals intersect at right angles.
Also, the non-vertex angles of a kite are congruent, that is they have equal measure.
Angle KPE and angle TPE in the given kite are right angles formed at the point of intersection of the two diagonals of the kite. They both equal 90 degrees.
Therefore, the true statement is:
D. KPE = TPE

Answer:
X=-1
Step-by-step explanation:
X=-1 is just a vertical line since it only tells where the x point is.
