Step-by-step explanation:
4 * 4 = 16
Answer:
15 cm since its half
Step-by-step explanation:
Step-by-step explanation:
the slope of a line is always the factor of x.
here : 1/2
it is the ratio y/x indicating how many units y changes, when x changes a certain angina amount of units when going from one point to another.
a perpendicular slope puts x and y upside-down and flips the sign.
here : -2/1 = -2
so, the equation looks like
y = -2x + b
b is the y-intercept, and we get this by putting the x and y coordinates of the given point into this equation and solve for b :
-1 = -2×-2 + b
-1 = 4 + b
b = -5
the full equation is therefore
y = -2x - 5
Answer:
Option "3" is the correct answer to the following question:
Step-by-step explanation:
Given:
Radius of cone (r) = 6 centimeter
height of cone (h) = 8 centimeter
slant height of cone (l) = 10 centimeter
Find:
Lateral surface area of the cone = ?
Computation:
⇒ Lateral surface area of the cone =
rl
⇒ Lateral surface area of the cone =
(6 centimeters) (10 centimeters)
⇒ Therefore, option "3" is the correct answer.
Answer:
Option C is correct
Volume of coffee in the thermos is, 150.8 cubic inches
Step-by-step explanation:
Volume of the cylinder is given by:

Where
V is the volume of the cylinder
r is the radius
h is the height of the cylinder respectively
As per the statement:
A thermos in the shape of a cylinder is filled with coffee.
the height of the cylinder is 12 inches and its radius is 2 inches
⇒ h = 12 inches and r = 2 inches.
Substitute the given values and use
in [1]
then;


Simplify:
V ≈150.8 inches.
Therefore, the volume of coffee in the thermos is, 150.8 cubic inches
