The diameter fits all the way across the circle, and the radius fits half way across the circle, thus making the radius half the length of the diameter so the ratio for diameter/radius would be 2/1 or 1/.5

Answer:

25.12cm

Step-by-step explanation:

So we first find the area of the circle on top:

area= $\pi$ $2^{2}$ or 3.14 x $2^{2}$

which equals 12.56

Then we multiply it by 2:

12.57 x 2 = 25.12

So the lateral surface area is 25.12cm
