Question
find the volume of a cylinder whose height is 7 cm and radius is 10 cmAnswer:soln
volume of cylinder= pie r ^h where pie = 22/7
height=7 cm
radius=10 cm
now,
volume of cylinder= 22/7*10*10*7cm
V≈2199.11cm³

Step-by-step explanation:
Answer:
x = number of cards that cost $2.50 each = 5
y = number of cards that cost $3.25 each = 1
Step-by-step explanation:
The equations are:
x + y = 6 (1)
2.5x + 3.25y = 15.75 (2)
From (1)
x = 6 - y
Substitute x = 6 - y into (2)
2.5x + 3.25y = 15.75 (2)
2.5(6 - y) + 3.25y = 15.75
15 - 2.5y + 3.25y = 15.75
- 2.5y + 3.25y = 15.75 - 15
0.75y = 0.75
y = 0.75/075
y = 1
Substitute y = 1 into (1)
x + y = 6
x + 1 = 6
x = 6 - 1
x = 5
Therefore,
x = number of cards that cost $2.50 each = 5
y = number of cards that cost $3.25 each = 1
Answer:
B. 22
Step-by-step explanation:
We know tan60=

Let common side be x
Tan = opp/adj= sqrt(3)

Transposing we get :

Now, we know that since the other triangle is a 45-45-90 triangle, we can state that the side adjacent to the given angle = 11 sqrt(2) as the two sides are equal due to the triangle being an isoceles triangle.
Solve for x by using Pythagorean theorem:



Hence answer is B. 22
Step-by-step explanation:
We know that,
1 m = 100 cm
the conversion from m² to cm² is as follows :
(1 m)² = (100 cm)² = 10000 cm²
A conversion factor between cubic meters and cubic centimeters is as follows :
(1 cm)³ = (100 cm)³
= 1000000 cm³
To convert m³ to cm³, multiply by 1000000.
Hence, this is the required solution.
