The volume of the cylinder is 508.68 cm²
<u>Explanation:</u>
Given:
Diameter, d of a cylinder = 6 cm
Radius, r = 6 / 2cm = 3cm
Height of the cylinder, h = 18 cm
Volume of the cylinder, V = ?
We know:
Volume of the cylinder = πr²h
On substituting the values we get:
V = 3.14 X (3)² X 18
V = 508.68 cm²
Therefore, the volume of the cylinder is 508.68 cm²
Answer:
trapezoid
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
(x + 3)^3/2 = 64
√(x + 3)^3 = 64
(x + 3)^3 = 64^2
(x + 3)^3 = (4^3)^2
(x + 3)^3 = (4^2)^3
Same exponent
So
x + 3 = 4^2
x + 3 = 16
x = 13
Answer:
The smaller angle is 45 degrees.
Step-by-step explanation:
Angles measure 180º. If there are two angles and one of them is three times the other, you would just divide 180 by 4.
The equation would look like:
3x + x = 180
First, the x would be added together:
4x = 180
Then, divide both sides by 4:
x = 45
