Answer: the height of the water after the sphere is placed in
it is 33.33 cm
Step-by-step explanation:
The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as
Volume = πr^2h
Where
π is a constant whose value is 3.14
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
r = 10 cm
h = height of water in the cylinder = 20 cm
Volume of water in the cylinder before the sphere was placed in it would be
V = 3.14 × 10^2 × 20 = 6280 cm^3
The formula for determining the volume of the sphere is expressed as
Volume = 4/3 πr^3
V = 4/3 × 3.14 × 10^3 = 4186.67cm^3
Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2
To determine the new height of the water,
10466.67 = 3.14 × 10^2× h
h = 10466.67/314 = 33.33 cm
Answer:
C
Step-by-step explanation:
The first part requires the intersection of the two sets, which means only the elements that can be found in both sets.
While the second part requires all the elements in both the sets.
14 minutes at 100 degrees
Answer:
Hight=7.04mt
Step-by-step explanation:
The area of a rectangle is the result of multiply two touching sides
Area=Length*Heght (1)
We have one its sides (2,6m).
The other side can be otained using the equation (1) where Area= 18.33 sqm
18.3sqm=2.6m* Height
Lets divide the whole expression by 2.6m
18.3 sqm / 2.6 m= 2.6m * Height
Hight=7.04mt
