Answer:
18312.5mm³
Step-by-step explanation:
Given parameters:
Height of cylinder = 18mm
radius = 18mm
Unknown:
Volume of the cylinder = ?
Solution:
The volume of cylinder is given as;
Volume = π r ² h
Insert the given parameters and solve;
Volume = 3.14 x 18² x 18
Volume = 18312.5mm³
Answer: All of them can be a triangle except for #11 because the two shortest sides don't add up to more than the longest side.
#10 is a Pythagorean Triple so it is a right triangle.
To determine if the triangle is an acute or obtuse triangle, we just need to plug the values into the Pythagorean Theorem. If the sum of the legs squared is greater than the hypotenuse, it's an acute triangle. If the sum of the legs square is less than the hypotenuse, it's an obtuse triangle.
Using this logic, 7 & 12 will be obtuse while 8 & 9 will be acute.
Answer:
=
Step-by-step explanation:
|-7| ? 7
well |-7| = 7
and the equation is 7 ? 7
And since 7 = 7, the symbol is =

Step-by-step explanation:
We are given the co-ordinates,
x : -2, -1, 0, 1, 2
y : 8, 5, 2, -1, -4
According to the graph, we see that this function represents a straight line.
The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.
So, taking any two points we will find the equation of the straight line.
Consider, (0,2) and (1, -1). Now, slope is given by,
m = 
i.e. m = -3
Now, we will find the y-intercept of this equation using (0,2) and m = -3,
i.e. y = -3x + c
i.e. 2 = c
Hence, the equation of the straight line is y = -3x + 2.
Answer:
8
Step-by-step explanation:
31 divided by 4 is 7.75. you cant have 7.75 boards so youd have to round up to 8
