Step-by-step explanation:
8 (12 + 30)
Follow PEMDAS order of operations.
Calculate within parentheses. (12 + 30)
12 + 30
12 + 30 = 42
= 42
=8 * 42
Multiply and divide left to right
8 *42
8 * 42 = 336
= 336

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
