Answer:
The formula of the volume of a cylinder is known as follow
<h2>V= πr²h</h2>
Where
π is 3,14 or 22/7.
d (diameter) is a straight line segment that crosses a center and connects two points on the circle.
r is the radius of the to part of the cylinder.
h is the height.
we can subsitute to our formula knowing that
d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm
V = πr²h
= 3,14 × 2² × 11
= 3,14 × 4 × 11
= 3,14 × 44
= 138,16 rounded off (138,2cm3) result
Its just a matter of subbing
-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)
so ur solution is (-2,2)
Answer:
i = 7
Step-by-step explanation:
13 - 3i = -8 -> -3i = -21 -> i = 7
23.8÷28=0.85
0.85 Liters
every liter is 1000 mililiters.
0.85 Liters is 850 mililiters.
Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees
