Find the areaRenata is completing a craft project that involves covering only the lateral surface of a cylindrical container with fabric. The cylinder has a height of 12.8 in. and a radius of 15.1 in. To the nearest square unit, how much fabric does she need for this project? Use a calculator.

Answers

Answer 1

Answer: Answer: Renata needs 1,214 square inches fabric for this project.

Data:
Height of the cylinder: h=12.8 in
Radius of the cylinder: r=15.1 in
Lateral surface of the cylinder: S=?

Solution:
S=2 Pi r h; Pi=3.1416

Replacing the known values:
S=2 (3.1416) (15.1 in) (12.8 in)
S=1,214.416896 in^2
S=1,214 in^2

It is said a picture is worth a thousand words. It is also claimed words are a dime a dozen. Assuming these propositions are true, what is the dollar value of a picture?

Answers

A picture is worth approximately $8.33, because you have to take a thousand divided 12 (dozen) which gives you 83.3333... than you take that dived by 10 since there is 10 dimes in a dollar and you get $8.33.

How do you calculate the circumference of a circle

Answers

$2\pi r$ where 'r' is a radius

You need to use the following equation - 2(pi) r . r = radius and so put the circle's radius in the equation and multiply!

What is the approximate volume of a tree trunk if the trunk is 13 feet tall with a circumference of 4.5 feet?A. 17.16 ft3
B. 21.17 ft3
C. 33.09 ft3
D. 27.14 ft3

Answers

The volume of the cylindrical trunk is calculated as approximately: B. 21.17 ft³.

What is the Volume of a Cylinder?

Volume = πr²h

The dimensions of the cylindrical trunk are:

Height = 13 feet
Circumference = 4.5 feet

Find radius (r) using the circumference of a circle formula:

4.5 = 2(π)r

4.5/2π = r

r = 0.7 feet

Volume of the cylindrical trunk = π(0.7²)(13) = 20.01 ft³ (close to 21.17 ft³)

The approximate volume of the cylindrical trunk is: B. 21.17 ft³.

#SPJ5

circumference = 2pi * r = 4.5
r = 4.5 / 2pi = 0.7162

Volume of a cylinder = pi * r^2 * h
= pi * (0.7162)^2 * 13
=20.95

which is approximately close to 21.17ft^3

Answer: 21.17ft^3
