Answer:
12.6
Step-by-step explanation:
To find the area of a cylinder, you find the area of the circular base and multiply it by the height. Remember that the area of a circle is pi*r^2. R, the radius, is 2. Putting this into a calculator and rounding to the nearest tenth, you get 12.6. Now that we have the circle, we multiply by the height. Since the height is 1, we have our answer of 12.6.

Answer:
3 , 4 , 5 can formed right triangle
Step-by-step explanation:
In any triangle if the sum of the squares of the smallest two sides equals the square of the third side, then the triangle is right triangle
∵ 16² + 32² = 1280
∵ 36² = 1296 ≠ 1280 ⇒ Not right Δ
∵ 3² + 4² = 25
∵ 5² = 25 ⇒ right Δ
∵ 8² + 12² = 208
∵ 16² = 256 ≠ 208 ⇒ Not right Δ
∵ 9² + 10² = 181
∵ 11² = 121 ≠ 181 ⇒ Not right Δ
