Answer:
7 feet
Step-by-step explanation:
Volume of a cyclinder = πr^2h
Volume of a cyclinder = 1952
π = 3.14
r = ?
h = 2r
Volume of a cyclinder = πr^2h
1952 = 3.14 * r^2 * 2r
1952 = 3.14 * 2r^3
1952 = 6.28r^3
Divide both sides by 6.28
r^3 = 1952 / 6.28
= 310.83
r^3 = 310.83
Find the cube root of both sides
r = 6.77 feet
Approximately 7 feet
Answer : The correct option is, (B) 56.8
Step-by-step explanation :
Right Triangle Altitude Theorem:
The measure of altitude drawn from the vertex of the right angle of a right angled triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.
We are drawing a line from vertex to hypotenuse side.
As per theorem:
Therefore, the length of the altitude to the hypotenuse is 56.8
Hey there! :)
Answer:
f(-2) = 2.
Step-by-step explanation:
To find f(-2), we simply need to look at the y value at x = -2.
At x = -2, the y value is equal to 2.
Therefore:
f(-2) = 2.
The simplified version would be 16x+3
12 units squared
Step-by-step explanation:
You realize that the shape can be divided into 3 shapes;
2 right-angled triangles (one small and one bigger one) and a rectangle. We can find the area of each and then sum them up. Because we are finding area under the shape, the negative signs will be ignored;
Larger right-angled triangle;
½ b * h
½ * 4 * 4 = 8
Smaller right-angled Triangle;
½ * b * h
½ * 2 * 2 = 2
Rectangle;
L * W
2 * 1 = 2
Sum of all the areas;
2 + 2 + 8 = 12
= 12 units squared
