Answer:
V = 83.0 cm^3
Step-by-step explanation:
To find the volume of the squared pyramid you use the following formula:
B: base of the pyramid = 19.6 cm^2
h: height of the pyramid = 12.7 cm
you replace the values of B and h in the equation ( 1 ):
hence, the volume of the pyramid is 83.0 cm^3
Octagon = 8-side polygon
<u>Find area of 1 triangle:</u>
Area of one side triangle = 60 ÷ 8 = 7.5 m²
<u>Given area and length, find height:</u>
Area of each triangle = 7.6 m²
Length of each triangle = 3m
Area = 1/2 x base x height
7.5 = 1/2 x 3 x height
Heigth = 5m
Answer: Slanted Height = 5 m

Answer:
Step-by-step explanation:
In the first equality
the matrices in both parts are the saem. The equality will be true if the same matrices are multiplied by the same numbers, so
For the second equality
if , then this equality represents the assotiative property of matrix addition.
Hence,
