Hello!
In math, a quadrilateral is a shape or figure that usually has 4 sides. For example, an example of a quadrilateral would be a square or a rectangle. A square or rectangle would be classified as a quadrilateral because a square and rectangle both are 4 sided shapes.
I hope this helps!
Answer:
see explanation
Step-by-step explanation:
(a)
Note the squared value in column 3 which is the square of 1 more than the row number, that is
row 2 → (2 + 1)² →3²
row 3 → (3 + 1)² → 4²
Find the square root of 676 = 26 → (25 + 1)² = 26²
Hence the row number is 25
(b)
The pattern in column 1 is [ row number × (row number + 2 ) + 1 ]
row number is n then n(n + 2) + 1 = n² + 2n + 1
Answer:
842.04 cm³
Step-by-step explanation:
Cylinder:
diameter = 6 cm
r = 6/2 = 3cm
h = 4 cm
Volume of cylinder = πr²h
= 3.14 * 3 * 3 * 4
= 113.04 cm³
Cube:
side = 9 cm
Volume of cube = side * side *side
= 9*9*9
= 729 cm³
Volume 0f composite figure = volume of cylinder + volume of cube
= 113.04 + 729
= 842.04 cm³
Answer:
400 cm² of stickers
Step-by-step explanation:
A wooden box has the shape of a rectangular prism.
To solve for the above question, we would be using the formula for the Surface Area of a rectangular prism to calculate how much stickers are required .
The formula for the surface area of a rectangular prism =
A=2(wl + hl + hw)
l = Length = 20cm
w = Width = 4cm
h = Height = 5m
Hence,
= 2 × (4 × 20 + 5 × 20 + 5 × 4)
=400 cm²
Therefore, 400cm² of stickers would be needed to cover the wooden box.
So each shirt would be like 300.333333333333
and each paint would be like 500.125
so 300 x 4
500 x 4
paints would be 2,000
and shirts would be 1,200
