Answer: the concrete cost for the pillar is $22947.12

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

The cylindrical concrete pillar has has a radius of 3 m and a height of 7 m. Therefore, the volume of concrete cylinder would be

Volume = 3.14 × 3² × 7 = 197.82 cubic meter

If concrete cost $116 per cubic meter, the cost of the concrete would be

116 × 197.82

= $22947.12

Answer:

$22,968

Step-by-step explanation:

To solve this question, we need to find the volume of the cylinder. Let’s call this V

Mathematically V = πr2h

where r = 3m , h = 7m and π = 22/7

Putting this in the formula:

V = 22/7 * 3 * 3 * 7 = 198 cubic meter

We are told concrete costs $116 per cubic meter. Hence, for 198 cubic meter we have 198 * 116 = $22,968

Answer:

8.245*10^6

Step-by-step explanation:

scientific notation is known as c*10^n

c : any number from 1-10

n : the power of base 10

the number in our case between 1 and 10 is 8.245

but then we want to move the decimal 6 spaces to the right, so we multiply that by 10^6

What's the answer to this problem
Artyom0805 [142]
So you have to subtract 115 from 15. Then you divide that number by 5 for each relative. That should give you your answer....$20
