A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.

first the focal is = 8cm/2 =4cm/2=2cmso 1/30+1/d= 1/2 1/d= 14/30= 2.14cm

3*8 cm = 24 cm.

82 mm is more precise because you are missing 0.2 for 8 cm. If you want your number in cm then 8.2 cm is just as precise as 82 mm.

15 cm and 8cm Solved with the help of Pythagoras' theorem and the quadratic equation formula.

Circumference of a circle: 2*p*radius or pi*diameter

It depends on the ratio of what of the circle? Its circumference, diameter, area?

The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm

radius=4cm diameter=8cm *radius is half the diameter

The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.

Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.

The radius is 1.27cm

the answer is 20.54

Just the one and it is 8cm by 14cm by 16cm

C=3.14*d<----diameter d=r*2 ex: what is the circumference of a circle if the radius is 4cm? 4*2=8cm 3.14*8=25.12cm c=25.12cm

C = ~25.133 cm
