Answer:
25/36 cm^3
0.69444... g/cm^3
Step-by-step explanation:
Find volume of cube: 4*12*3
144 cm^3
Rember the density formula: g/cm^3
subsitute:
100g/144cm^3
simplified 24/36 cm^3
0.69444... g/cm^3
Answer:
V = πr²h
To determine the volume of a cylinder you have to multiply the area of the base by the height of the cylinder.
Step-by-step explanation:
The base of a cylinder is a circle. So we must find the area of the circle first. (Which is πr²)
Then we multiply the height by the area of the circle.
V = π·r²·h
This can be used in different ways as well,
if we don't know the radius but know everything else we could use the formula:
(r = √(V/πh))
If we don't know the height we use this formula:
(h = V/(πr²))
Answer:
Step-by-step explanation:
5x² times 6 is : 30x²
Answer:
30°,60°,90°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>As </u><u>we</u><u> know</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>,</u>
- x + 2x + 90 = 180
- 3x = 90
- x = 90/3
- x = 30
