The diameter is six cm.
A 3 centimeter diameter circle has an area of 7.068 cm2
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
Assuming this is a rectangular block, you are supposed to multiply the three numbers.
2x3x2=12cm3
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter
The diameter is six cm.
circumference = pi x diameter = 3.1416 x 3cm = 9.42cm (approx)
A 3 centimeter diameter circle has an area of 7.068 cm2
An isosceles triangle
30 cm3
it is "1 == 2"
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
A mars bar is 9.5cm x 3cm x 2cm.
The radius would be HALF the diameter, making the answer 1.5cm ! The diameter of a circle is the distance across it, passing through the centre. The radius is the distance from the centre to the edge.
10cm 2l + 2w 4+6=10cm
Assuming this is a rectangular block, you are supposed to multiply the three numbers.
