Answer:
C = $33,057.92
The cost of the pillar is $33,057.92
Step-by-step explanation:
Given;
Radius of the concrete r = 4 m
Height h = 7 m
Cost per volume R = $94 per cubic meter
π = 3.14
The volume of the cylinder shape concrete is;
V = πr^2 h
Substituting the given values;
V = 3.14×4^2 × 7
V = 351.68 m^3
The cost of the pillar is C;
C = Volume × cost per volume
C = V × R
C = 351.68 m^3 × $94 per cubic meter
C = $33,057.92
The cost of the pillar is $33,057.92
Answer:
c+10=3
c=7
Step-by-step explanation:
10 more than c is the same as 10 plus c
10+c=3
10=3-c
7=c
Brainleist would be appreciated
photo math is the solution of your problems hehehehehehe try it!!!
Answer:
It doesn't form a right triangle
Step-by-step explanation:
According to the Pythagorean theorem, 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.
a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.
10^2 + 15^2 = 20^2
100 + 225 = 400
325 =/= 400
This is false.
Since this is not equivalent, it is NOT a right triangle.
Hope this helped :)
