Answer:

The cost of the pillar is $22,947.12

Step-by-step explanation:

Diameter of the pillar = 6m

Radius = diameter / 2 = 6 / 2 = 3m

Height if the pillar = 7m

Volume of the pillar = πr²h

π = 3.14

V = 3.14 × 3² × 7

V = 3.14 × 9 × 7

V = 197.82m³

Volume of the pillar is 197.82m³

If 1m³ = $116

197.82m³ will cost $x

X = (197.82 × 116) / 1

X = $22,947.12

The cost of the pillar is $22,947.12

a plumber uses the expression 48+25h to determine the number of dollars to charge each customer. If h=4, how much does the custo
Elis [28]

Answer:

$148

Step-by-step explanation:

We are given the expression:

48+25h

We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.

48 + 25h (h=4)

48 + 25(4)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

First, multiply 25 and 4.

48+ (25*4)

48+100

Next, add 48 and 100

48+100

148

The customer will have to pay $148

IN URGENT NEED OF HELP. PLEASE HELP.
Firlakuza [10]

Answer:

533 sq. ft.

Step-by-step explanation:

First find the area of the rectangle on the bottom:

22*13=286

Then in your head move the triangle on the right to the other side to create a triangle (if this doesn't make sense tell me in a comment)

It will turn into a rectangle that is 13 by 19 so find the area of that:

13*19=247

Then add the areas together:

286+247=533
