Answer:
0.905 in
Step-by-step explanation:
Parameters given:
Volume of cone, V = 3.6 in³
Height of cone, h = 4.2 in
Although the diagram is not shown, this problem can be solved.
The volume of a cone is given as:
V = ⅓ * π * r² * h
r is the radius of the base of the cone
We can find r.
3.6 = ⅓ * π * r² * 4.2
3.6 = 4.399 * r²
=> r² = 3.6 / 4.399
r² = 0.8184
=> r = 0.905 in
The radius of the base of the cone is 0.905 in.
Answer:
(−1.5,1)
Step-by-step explanation:
Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (6,7) and p2 (-9,-5)
The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula
d = √ ((X2-X1)2+(Y2-Y1)2)
d = √ (-9-6)2+(-5-7)2
d = √ ((-15)2+(-12)2)
d = √ (225+144)
d = √ 369
The distance between the points is 19.2093727122985
The midpoint of two points is given by the formula
Midpoint= ((X1+X2)/2,(Y1+Y2)/2)
Find the x value of the midpoint
Xm=(X1+X2)/2
Xm=(6+-9)/2=-1.5
Find the Y value of the midpoint
Ym=(Y1+Y2)/2
Ym=(7+-5)/2=1
The midpoint is: (-1.5,1)
Answer:
x = 16.2
Step-by-step explanation:
5/9 = 9/x
5x = 81
x = 16.2
