Answer:

Step-by-step explanation:
The trash can has a cylinder shape, so we have to calculate the volume of a cylinder.
The volume of a cylinder is given by the formula

where
V is the volume
r is the radius of the base
h is the height of the cylinder
In this problem, we have:
h = 24.90 in. is the height of the can
d = 15.50 in. is the diameter of the can, so the radius is half of this value:

Therefore, the volume of the trash can is:

1/3 divided by 1/4= 4/3
The method for dividing fractions is keep change flip.
Keep the 1/3, change the division sign to multiplication sign, flip the 1/4 to a 4/1, then solve.
Answer: Since 10° is less than 90, we can express this in terms of a co-function. cos(θ) = sin(90 - θ) cos(10) = sin(90 - 10) cos(10) = sin(80)
Step-by-step explanation: Note that cos10° is periodic: cos (10° + n × 360°) = cos 10 degrees, n . There are more formulas for the double angle (2 × 10°), half angle ((10/2)°) as well as the sum, difference and products of two angles such as 10° and β.
