All 4 sides of a square are of the same length.
The formula for the area of a square is s*s = area where s is the length of one side of the square.
s^2 = 81
s = 9 or -9
-9 does not apply here but 9 does.
Each side of the square deck is 9 feet long.
A: 7:2
35/7=5
10/2=5
the others don’t equal the same thing
Both triangles area:
4.2 x 8.2 = 34.44
you don’t need to divide by two cause there’s two triangles anyways.
also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)
rectangle:
4.2 x 5.3 = 22.26
the total area is 56.7cm squared
Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
