Solve for height

Mathematics
1 answer:
Leno4ka [110]3 years ago
8 0
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.

so if we are given a radius of 2 cm and a volume of  180 cm^3 we work out the height as follows:-

180 = pi  * 2^2 * h

h =   180 / (pi*2^2)

height  h  =  180 / 4pi =  14.32 cm  to nearest hundredth

A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line.
sineoko [7]
Easy, find the equation of the line,

Using y=mx+b form:

(-1,3) m=2

3= 2(-1)+b

3= -2+b
+2     +2

5=b

y=2x+5. This is your equation.

Now, plug in the coordinates:

(-3,2)

2= 2(-3)+5
2= -6+5
2= -1

NO

(0,5)

5= 2(0)+5
5=5

YES

(1,5)

5= 2(1)+5
5= 2+5
5=7

NO

(1,4)

4= 2(1)+5
4= 2+5
4=7

NO.

Thus, B, is your answer.
