Answer:
485.9 mm³
Step-by-step explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
V = (2 / 3) π r³
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
V=π(4)²(7)
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
V = 128π/3 + 112π
= 485.9 mm³
Answer: 9=h
Step-by-step explanation:
The formula of an area of a triangle is A=1/2(b)(h)
In the problem, you were given that
b=16
h=x
A=72
Then pluge b, h, A in the equation of A=1/2(b)(h).
72=1/2(16)(h)
Simplify
72=8(h)
72/8=8(h)/8
9=h
Answer:
d !
Step-by-step explanation:
25×5 = 125, 125-1 = 124
the two opposite sides are the same angle meaning they both must equal 124
i hope this helps :)
Answer: Zander Runs, 13.125 miles. You take the mixed number and change it into an improper fraction. So you get 63/4 then multiply that by 5/6 and get 13.125 miles there is your answer. I hope this helps you
Step-by-step explanation:
Answer:
0=0 True for all x
Step-by-step explanation:
4x3/5=12x1/5
Refine and expand
12/5x=12/5x
multiply both sides by 5
simplify
12x=12x
subtract 12 from both sides
0=0 True for all x
