The formula for the volume of a pyramid is:
Volume=(1/3)*(Area of the base)*(Height of the pyramid)
You stated that the pyramid has a 10 by 10 base, so the "area of the base" is 100 squared feet. Also, you stated that the "height of the pyramid" is 8.5 feet.
So, Volume=(1/3)(100 squared feet)(8.5 feet)
V=(1/3)(850 cubic feet)
V=283.33333..... cubic feet
Answer:
BC ≈ 11.9 cm
Step-by-step explanation:
We use sin∅ (opposite over hypotenuse) to solve for our missing length:
sin58° = BC/14
14sin58° = BC
BC = 11.8727
The answer is x=2 because you have to subtract 7 on both sides so you get -3x=-6 then to get x alone you have to divide by -3 because a negative and a negative divided together makes a positive so you divide -3 to both sides and you get x=2
Answer:
Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that
Multiply both sides by 5
Multiply both sides by Area{circle}
Substitute the areas of sector and circle with their respective formulas;
So, we have
Divide both sides by
Multiply both sides by 360
Divide both sides by 5
Hence, the central angle is 216 degrees
