I am guesing you are talking about a cylinder. if you are it is 1326.65 cm2, assuming that pi is only 2 decimal places or 3.14.
Calculate it by multiplying the value of Pi by twice the radius - then multiplying that number by the height... I'll leave YOU to do the maths !
Formula for the volume of a cylinder... Pi x Radius (squared) x Height !
Radius = diameter/2 = 5 cm
Half the base times the height = 15cm2
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
The radius of a cylinder that has a volume of 350cm and a height of 10cm is: 3.34 cm
The Volume of cylinder with radius of 4cm and height of 10cm is: 502.65 cm3
Calculate it by multiplying the value of Pi by twice the radius - then multiplying that number by the height... I'll leave YOU to do the maths !
The volume is 1130.97 cm3
V = 2,011 cm3
Height = Volume / π r2 Volume = 2 litres Radius = 10 cm Height = 6.37 cm
Label t radius 6cm the height 8cm and the slant height 10cm
r = 3.989 cm
Volume = length * width * height = 10cm * 5cm * 2 cm = 100 cm3 Density = mass/volume = 300g/100cm3 = 3 grams per cm3.
This cylinder has a radius of approximately 4.0cm
h = 5 cm (4.9975 cm)
The surface are of a cylinder whose radius is 10cm and height is 20cm is 1884.96cm2
