What is the mean of 4cm 2cm 1cm 3cm 5cm?
Mean = sum(X)/n = 15cm/5 = 3cm
If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What is the volume of a 2cm x 2cm x 2cm cube?
It is 8 cubic cm.
What is the volume of a prism whose dimensions are 2cm x 2cm x 2cm?
8 cm3 i hope this isn't for your homework
What is the perimeter of a rectangle 2cm x 15cm?
It is: 2+15+2+15 = 34cm
How many different rectangles can you draw with a perimeter of 16 cm?
It depends what units you use for each side ! A 1cm x 15cm rectangle has a perimeter of 16cm. So does a 2cm x 4cm one ! If you start using millimetres, there are many more possibilities !
What is the mean of 4cm 2cm 1cm 3cm 5cm?
Mean = sum(X)/n = 15cm/5 = 3cm
What is the perimeter of 8cm and 15cm?
Perimeter is the total of all the sides. Let's assume your part-question relates to a rectangle. Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...
What is the perimeter of a square with a side of 2cm?
8cm (4 x 2 = 8)
If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
What is the perimeter of a square if it has an area of 4cm square?
Since all four sides are equal in a square, a square with an area of 4cm2 must be 2cm on each side. Therefore, the perimeter is 2cm x 4 = 8cm.
What is the perimeter of a regular hexagon with side lengths of 15cm?
90cm (six sides x 15 = 6 x 15 = 90)
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
How do you measure perimeter of 6cm x 2 cm?
A 6cm X 2cm shape is a rectangle. Two sides are 6cm, and the other two are 2cm. Therefore, 6+6 + 2+2 = 16cm.
Volume of a cube 2cm by 2cm by 2cm?
A cube has all sides of length 2cm. What is the surface area and volume of the cube?
What is the volume of a 2cm x 2cm x 2cm cube?
It is 8 cubic cm.
