What is the volume of the cone shown above ? If H = 2 and R= 9

1 answer:

6 0

For this case, the first thing you should do is apply the following formula:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Substituting values we have:
V = (3.14 * (9 ^ 2) * 2) / (3)
V = 169.56
Rounding:
V = 169.6 units ^ 3
Answer:
the volume of the cone is:
B. 169.6 units cubed

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)

LUCKY_DIMON [66]

Answer:

$y + 6 = -2 (x-4)$

Step-by-step explanation:

Point-slope formula is represented by the equation $y-y_1 = m (x-x_1)$ . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the $m$ , $x_1$ , and $y_1$ for real values.

The $m$ represents the slope of the line. Since we know the slope is -2, substitute -2 for $m$ . The $x_1$ and $y_1$ represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for $x_1$ and -6 for $y_1$ . This gives the following answer and equation:

$y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)$

Surface area of a cylinder radius=10 height=15

Virty [35]

Answer:

1570

Step-by-step explanation:

the formula for surface area of a cylinder is:

A= 2πrh + 2πr²

π aka pi = 3.14

r = 10

h = 15

so now plug in the numbers

A = 2(3.14)(10)(15) + 2(3.14)(10²)

A = 942 + 2(3.14)(100)

A = 942 + 628

A = 1570
