A storage tank holds 235,500 in3 of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical containers, each with a radius of 5 in. What is the height of the cylindrical containers? Use 3.14 to approximate pi.

Answers

Divide 235.500 by 25 containers = 9420 in^3 per small container

Volume of a cylinder: Pi*(radio)^2*height = 3.14*(2.5in)^2*height = 9420 in^3

Then height = 9420 in^3/(3.14*6.25in^2) = 480 in.

Answer: 480 in.

The diameter of a flour tortilla is 12 inches. What is the area to the nearest hundredth?

Answers

Answer:

The area of flour tortilla is:

113.04 square inches.

Step-by-step explanation:

The flour tortilla is in the shape of a circle.

Hence we need to find the area of as circle whose diameter is 12 inches.

As we know that the diameter and radius are related as:

Diameter=2×Radius.

This implies,

12=2×Radius

⇒ Radius=6 inches.

The area of circle is given as:

Area=π×(Radius)²

=3.14×6²

=113.04 square inches.

Hence, the area of flour tortilla is:

113.04 square inches.

Answer:

113.04

Ross needs to buy a countertop for a laundry room. He calculated the area to be 12 square feet. The actual area is 11.8 square feet. What is Ross's percentage error?

Answers

The formula for percentage error is:

$\sf{Percentage~ error= (|Approximate ~-~ Actual|)/(|Actual|)}$

Ross got the approximate area as 12, while the actual area was 11.8. So, let's plug it in to the formula.

$\sf{Percentage~ error= (|Approximate ~-~ Actual|)/(|Actual|)= (|12-11.8|)/(|11.8|)= (|0.2|)/(|11.8|)= (0.2)/(11.8) \approx 0.0169 }$

Multiply 0.0169 by 100 to make it into a percent.

0.0169 * 100 = 1.69%

Ross's percentage error is 1.69%.

Answer: B - 1.69%
