The area of a circle that has diameter of 3 cm is: 7.069 cm2
The diameter of the sphere is 19.6 cm.
Since with circles the radius is half the diameter, the diameter would be 6 cm.
1.8 cm The radius is half of the diameter.
the radius is half of the diameter, so 6 cm
1.5cm
Since the density of aluminum is 2.7 g cm-3, a sample with a mass of 5.4 would have a volume of 2 cm3.
diameter = 5/pi = 1.591549431 or 1.592 cm rounded to 3 d.p.

No current circulating British coin has a diameter of exactly 3 cm. The closest is the £2 coin with a diameter of 2.84 cm.
diammeter*pi= 10 divide both side by pi to find the diameter: diameter = 3.183098862 or 3 cm to the nearest cm.
