ok i searched it up thers some good choices just once search it up if u dont under stand it ill help u

Do you have more information about your question? You wrote "A cylinder 6yd and 20yd" What is this the measurement of? is it the diameter? the radius or length?

3. marigirl

Is there anyway I could see the question? Because we dont know is the 6yd (for the cylinder) is the diameter or the radius ? amusing the longer measurement of 20yd means the height of the cylinder

You can take a screen shot and attach it here. See the 'attach file' button below

ok

6. marigirl

did u mean its saved to your computer?

7. marigirl

yay! we got it. so we are doing question 4?

Okay so you can see for the Cylinder 6yd is actually the Radius (Diamater means from one end of the circle to the other and Radius means half of that) and 20 yd is the length of it.

Surface Area of Cylinder: There are 3 parts which make up a Cylinder. 2 circles and a rectangle |dw:1444118216363:dw| Think of the label of a food can to help you visualise this

The Surface Area of Cylinder: Area of Circle=$\pi r^2$ Area of Circle=$3.14\times6^{2}$ Area of Circle=113.04 Remember we need two circle. Now for the rectangle Area of rectangle=$base \times height$ Area of Rectangle=$circumference of cirle \times 20$ Circumference means measurement around the circle Area of Rectangle=$2 \pi r \times 20$ Area of Rectangle=$2 \times 3.14 \times 6 \times 20$ Area of Rectangle=753.6 Surface Area of Cylinder= 113.04+113.04+753.6=979.68

Dont forget to round your answers to the nearest tenth and also you need Volume Volume of Cylinder= $\pi r^2 \times h$ which is $3.14 \times 6^2 \times 20$
