We can use a trigonometric function to solve for angle C. We can use any of the trigonometric functions to solve, but today let's use tangent.
Since we know the dimensions of the opposite and adjacent legs, we can solve for theta directly:
- but this is in radians. So we must convert to degrees.
Therefore, the measure of angle C is 28°.
Answer:
32901 gallons
Step-by-step explanation:
First, we find the volume of the cylindrical water tank when it is full.
The volume of a cylinder is given as:
V =
where r = radius and h = height of the cylinder
The diameter of the tank is 20 feet, hence, its radius is 10 feet.
Volume, V, is therefore:
V =
This is the volume of the tank, when it is full.
When it is 70% full, the volume will be:
1 cubic foot () is 7.48 gallons.
Therefore, the volume of the 70% full tank in gallons will be:
4398.23 * 7.48 = 32901.05 gallons ≅ 32901 gallons
The tank contains 32901 gallons of water.
Answer:
3 pizza slices.
Step-by-step explanation:
We have been given that Desmond ordered his favorite pizza with 12 slices. Sadly, he could finish only 75% of the whole pizza.
As Desmond ate 75% of 12 slices, so left number of slices will be equal to 25% of 12 slices.
Therefore, 3 pizza slices were left.
