Answer: 135cm
Step-by-step explanation
Volume of a cylinder = πr²h
Volume of a cone. = 1/3πr²h
The two shapes are both solid shapes.
Since the have same volume, we can then equate the two together and solve for the height of the cone.
Now make H the height and R the radius of the cylinder and h the height and r the radius of the cylinder.
Now equating the two
πR²H = 1/3πr²h
Now substitute for the values now
Multiply through by 3
3πR²H = πr²h
But π is common so it could be obliterated from the equation
3R²H = r²h
3 x 12² x 20 = 8² x h
3 x 144 x 20 = 64 x h
60 x 144 = 64h
8640. = 64h
Therefore
h = 8640/64
= 135cm
Answer:
C 117
Step-by-step explanation:
<2 = 63
<4 = <2 vertical angles
<4 + <7 = 180
63 + <7 = 180
subtract 63 from each side
<7 = 117
12 people plus herself is 13 people. So 13.75(13)=178.75.
So, $178.75 for all tickets. But... I might be wrong.
This equals: x^3 + 5x^2 - 4x - 20
making the degree 3, the LC 1, and the y-int 20

Answer:
Here is the answer
Step-by-step explanation:
Apples in 1 baskets=100
Apples in 64 baskets=100*64-6400
apples (before adding 30 apples in each
basket).... ..(1)
Some apples left unpacked
So he added 30 apples to each
Total apples added by him- 30*64(in each basket*no of baskets)
= 1920 apples
.(2)
So total no apples eq(1)+eq(2)
= 6400 apples + 1920 apples
=8320 apples packed in total
Therefore the total no. of apples packed were 8320 apples.
Hope this helps
Thanks
