Find the volume of a pyramid with a square base, where the side length of the
base is 8.7 cm and the height of the pyramid is 13.1 cm. Round your answer
to the nearest tenth of a cubic centimeter.
Answers
Answer: V= 330.513 cm 3
Step-by-step explanation:
Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so
8.7 x 8.7 = 75.69cm^2
75.69 x 13.1 = 991.539
991.539 ÷ 3 = 330.513 cm^3

Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )

What is Pythagoras theorem?The Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Given is a square, with diagonal of 6 units we need to find the measure of the sides, of the square,
By the definition of the Pythagoras theorem,
s² + s² = 6²
2s² = 36
s² = 18
s = 3√2
Therefore, we get s = 3√2
Hence, the measure of the sides, of the square, is 3√2 units

help the volume of the roller is 576cm. Calculate the height and area of the roller if its radius is 8cm.
Answers
Answer:
143.7cm^2
Step-by-step explanation:
Given data
Volume= 576cm^3
Radius= 8cm
The expression for the volume of cylinder is
V= πr^2h
substitute
576= 3.142*8^2*h
576= 3.142*64*h
576= 201.088h
h= 576/201.088
h=2.86cm
The formula for finding the lateral area of a right circular cylinder is:
A=2πrh
substitute
A= 2*3.142*8*2.86
A= 143.7cm^2
Hence the area is 143.7cm^2
