Answer:
The volume of the cone is 314yd³
Step-by-step explanation:
radius = half of diameter
d = 10yd
r = 10yd / 2 = 5yd
First of all to solve this problem we have to know the formula to calculate the volume of a cone
v = volume
r = radius = 5yd
h = height = 12yd
π = 3.14
v = 1/3 * π * r² * h
we replace with the known values
v = 1/3 * 3.14 * (5yd)² * 12yd
v = 1/3 * 3.14 * 25yd² * 12yd
v = 314yd³
The volume of the cone is 314yd³
Hello there!
The correct answer is option B
2x² + (4x - 6x²) + 9 - (6x + 3)
Just take them out of the parentheses
2x² + 4x - 6x² + 9 -6x - 3
Combine like terms
2x² - 6x² + 4x - 6x - 3 + 9
= -4x² - 2x + 6
Thus,
The correct answer is option B
I think the answer for 6x-4y=30 is -1.5
Answer:
117°
Step-by-step explanation:
Angle of straight line is 180°
Angles in a triangle add up to 180°
starting at right
180 - 101 = 79° at right side angle in triangle
now solving left side angle
180 - 38 - 79 = 63°
now solving x using left side angle, must add to 180°
x + 63 = 180°
x = 117°
Answer:
Thus, 3/2 in, or 1.5 in, represents 1 mile.
Step-by-step explanation:
"3 quarter inches to the half mile" can be expressed as "3/4 inch to 1/2 mile."
Write and solve an equation of ratios to obtain the unit rate in inches/mi:
3/4 in x
---------- = ---------
1/2 mi 1 mi
Cross multiplying, we get 3/4 in-mi = (1/2) mi*x.
Solve this for x by mult. both sides by 2:
6/4 in-mi = x mi
and then dividing both sides by mi:
(6/4) in-mi
--------------- = 3/2 in
mi
Thus, 3/2 in, or 1.5 in, represents 1 mile.
