A silo is a building shaped like a cylinder used to store grain. The diameter of a particular silo is 6.5 meters, and the height

Hey there! I'm happy to help!

To find the volume of a cylinder, you multiply the base by the height.

First, we find the base. The base is a circle. To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14). The radius is half the diameter.

6.5/2=3.25

We square this.

3.25²=10.5625

And multiply by 3.14

10.5625(3.14)=33.16625

Now we multiply this by the height.

33.16625(12)=397.995

Therefore, the volume of this silo is 397.995 cubic meters.

Have a wonderful day! :D

Jessica assembles a product that requires the insertion of 3 aluminum pins. She can assemble approximately 15 products per hour.

larisa [96]

If she can make 15 per hour that would mean that each hour she is making 15 cans.

She has 6 hours that means that she will make 90 products.

How To Do The Math: 15<span>×6=90

Since we are finding out how many pins she need and not haw many products we will have to check how many pins she will need per product.

She needs 3 pins per product.

Since she will be making 90 products all we have to do is multiply 90 by 3 which will equal 270.

How To Do The Math:90</span><span>×3=270

Your Answer will be 270 Pins.</span>

Need the answer no is able to give me the right answer

Given:

The window is divided into a semi-circle and a rectangle.

The radius of the semi-circle is 2' 9''.

The length of the rectangle is 5; 6''.

The cost of put molding for the curved portion is $10.82 per foot.

The cost of put molding for the straight portion is $ 2.81 per foot.

Required:

We need to find the cost to put molding for the window.

Explanation:

Convert inches to feet.

$We\text{ know that 1 foot =12 inches.}$

Divide 9 inches by 12 to convert inches to feet.

$9\text{ inches=}\frac{9}{12}feet=\frac{3}{4}feet.$ $2^{\prime}9^{\prime}^{\prime}=2+\frac{3}{4}=\frac{8+3}{4}=\frac{11}{4}feet.$ $The\text{ radius of the semi-circle, r =}\frac{11}{4}feet.$

Divide 6 inches by 12 to convert inches to feet.

$6\text{ inches=}\frac{6}{12}feet=\frac{1}{2}feet.$ $The\text{ length of the rectangle is, }l=5+\frac{1}{2}feet=\frac{11}{2}feet$

The width of the rectangle is the same as the diameter of the semi-circle.

$d=2r=2\times\frac{11}{4}=\frac{11}{2}feet.$ $The\text{ width of the rectangle is, w=}\frac{11}{2}feet.$

Consider the arc length of the semi-circle formula.

$S=\pi r$

$\text{ Substitute }r=\frac{11}{4}\text{ and }\pi=3.14\text{ in the formula.}$ $S=3.14\times\frac{11}{4}$ $S=8.635feet.$

Multiply the arc length by $10.82 to find the cost of put molding for the curved portion.

$The\text{ cost of the curved portion=8.635}\times10.82$ $The\text{ cost of the curved portion=\$ 93.4307.}$

The perimeter of the straight portion is the sum of the three sides of the rectangle.

$P=l+w+l$ $Substitute\text{ }l=\frac{11}{2\text{ }}feet\text{ and }w=\frac{11}{2}feet\text{ in the formula.}$ $P=\frac{11}{2}+\frac{11}{2}+\frac{11}{2}$ $P=16.5$

Multiply the perimeter by $2.81 to find the cost of put molding for the straight portion.

$The\text{ cost of the straight portion}=16.5\times2.81$ $The\text{ cost of the straight portion}=46.365$

The cost to put molding around the window is the sum of the cost of the curved portion and straight portion.

$The\text{ cost to put molding around the window}=\text{ \$93.4307+ \$}46.365$ $The\text{ cost to put molding around the window}=\text{ \$139.7957}$ $The\text{ cost to put molding around the window}=\text{ \$139.80}$

Final answer:

$The\text{ cost to put molding around the window}=\text{ \$139.80}$
