The radius will stay as 1cm but the area of a circle is: pi times radius squared
2cm; the diameter of a circle is twice its radius.
3.14 square cm
V = 9.42478 cm3
The radius is in the question 1cm the volume is pi * R^2 * H = pi *1 ^ 1 * 5 = 5 * pi surface area pi * 2 * R * 5 + 2 * ( pi * r ^2) = 10 * pi + 2 * pi = 12 * pi
The area of a circle 1cm in diameter is determined by the formula Pi x Radius x Radius. Radius is 5mm Pi is 3.14159 (roughly) So the area is 3.14159 x 5 x 5 Which is 78.5398163397448 square mm.
0.5 cm
The radius is half the diameter = 1cm
2cm; the diameter of a circle is twice its radius.
1cm
V = 4.19 cm3
3.14 square cm
8mm
V = 9.42478 cm3
The radius is in the question 1cm the volume is pi * R^2 * H = pi *1 ^ 1 * 5 = 5 * pi surface area pi * 2 * R * 5 + 2 * ( pi * r ^2) = 10 * pi + 2 * pi = 12 * pi
The volume of a cylinder is V=PI*r2*h The radius of the cylinder is 3 cm and the height would be 1cm So V = PI*(3cm)2*(1cm) V is approx. 28.3 cm3
The area of a circle 1cm in diameter is determined by the formula Pi x Radius x Radius. Radius is 5mm Pi is 3.14159 (roughly) So the area is 3.14159 x 5 x 5 Which is 78.5398163397448 square mm.
Any shape you want as long as the area within its boundary is 6cm2.examples:a triangle of base 6 cm and height 2 cm;a rectangle 2cm by 3 cm;an L shaped hexagon with sides 5cm, 2cm, 1cm, 1cm, 4cm, 1cm;circle of radius approx 1.382 cm;
