You said "diameter", so we'll assume that you're talking about a circle.
Circumference of a circle (distance around, 'perimeter') = (pi) x diameter = 6 pi = 18.85 cm (rounded)
Area of a circle = (pi) R2 = (pi) x (1/2 of the diameter)2 = 9 pi = 28.27 cm2 (rounded)
A ≈ 28.27cm2
A cylinder with a height of 7cm and a diameter of 6cm has a surface area of 188.5cm2
Its perimeter is the sum of its 6 sides
The exact area = pi*32 or 9*pi square cm
The length should be 6cm and the width is 4cm.
A ≈ 28.27cm2
The area is 28.274 cm2
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
Area 42 cm2, perimeter 26 cm.
A square with a perimeter of 24 cm has an area of: 36 cm2
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
Your square must have sides of 6cm so perimeter is 24cm.
16 cm
The circumference of a circle with a diameter of 6cm is about 18.85cm
The perimeter of a rectangle whose length is 5cm wit a width of 6cm is 22cm
A right angle triangle fits the dimensions given
A sphere with a diameter of 6cm has a volume of 113.1 cm3
