Surface area of cylinder is 2(pi)r^2 + 2(pi)rh
r=5cm
h=18cm
*fill in
50pi + 180pi = 230pi

Jordan builds a miniature catapult for the science fair. He documents how far the catapult can throw a small rock for his report
GrogVix [38]

The rate to convert yards to meters is

1 \text{ yard}=0.9144\text{ meters}

So, if you multiply both sides by 8, you get

8 \text{ yards} = 8\times 0.9144 = 7.3152 \text{ meters}

To round the answer to the nearest tenth, we need to choose between 7.3 and 7.4. Since the hundreths digit is 1, which is less than 5, 7.3 is nearest to 7.3152 than 7.4, so the correct answer is 7.3

A closed cylindrical tank of radius 1.50m and height 300cm, is made from a metal sheet. How much sheet is required?
Anika [276]

Answer: 13.5π≈42.41

Step-by-step explanation:

Basically it is asking for the circumference of this cylinder.

#1 Find the circumference of the circle base

Formula to use: 2πr

2πr=2π(1.5)=3π

---------------------------

#2 Find the area of the circle base

Formula to use: πr²

πr²=π(1.5)²=2.25π

--------------------------

#3 Find the area of body of the cylinder

Formula to use: lw

300cm=3m

l (length)= 3π (since the body of the cylinder the basing on the circumference of the circle base)

w (width)= 3

lw=3π×3m=9π

----------------------------

#4 Add all of them together

There are 2 base and one body

2.25π×2+9π=13.5π

105 in radiu is equa to answer fast​
Dafna1 [17]

Answer: I would assume you mean 105 in radius to diameter which would be 210 since diameter is just radius times 2. <u>Otherwise, explain the question more since it's barely legible.</u>

Solve each inequality.<br> X+5 &lt; 6 <br> Pls help
agasfer [191]

Answer:

x<1

Step-by-step explanation:

You would just subtract 5 from both sides of the equation. The sign does not flip because you are not multiplying or dividing any negative number across the sign.  So simply x+5 (-5) < 6 (-5). On the left side the 5 would cancel out.  on the other side 6-5 is equal to 1.

Answer:  x<1
