Answer:
V =113.04 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = 3.14 (3)^2 4
V = 3.14 *9*4
V =113.04 cm^3
Step-by-step explanation:
x + x + x = 90°
3x = 90°
x = 90/3 = 30
x = 30°
now,
apply angle sum property to find the value of y
as, x = 30
so,
30 + 90 + y = 180
120 + y = 180
y = 180 - 120 = 60
y = 60° ans.
therefore, option B is correct
hope this answer helps you!
Answer:
D) MNO
Step-by-step explanation:
A) and B) are over the y axis
C) is over both axes
D) is correct: it is a reflection over the x axis.
Answer:
The volume is 140 cm3. See the explanation below, please
Step-by-step explanation:
We use the formula:
Volume (V) = 4/3 pi r ^3
V= 4/3x 3, 14x (6,44/2)^3 = 139,8 cm3= 140 cm3
The answer is Y = -1/2x + 60
