The area of a circle is figured out using the formula

Now, the circle we are given has a radius of 9cm. So, the area of the circle would be:

Area = 3.14 x (9)2

= 3.14 x 81

= 254.34 cm2

The area of the circle in question is 254.34 cm2

The opposite of a square root is the square of a number. In mathematical terms, if the square root of a number x is denoted as √x, then the opposite of the square root (√x) is x itself. This is because squaring a number undoes taking the square root of that number.

Oh, what a happy little question! To find the number of combinations in 123, you can use a simple formula: n! / r!(n-r)!. In this case, n=3 and r=3, so it would be 3! / 3!(3-3)! which simplifies to 6 / (6*1), giving us 1 combination. Just remember, there are no mistakes, just happy little accidents in math!

Answer 9/11

The notation (9C4) represents the number of combinations of 9 items taken 4 at a time. It is calculated using the formula ( \frac{n!}{r!(n-r)!} ), where ( n ) is the total number of items, ( r ) is the number of items to choose, and ( ! ) denotes factorial. Therefore, ( 9C4 = \frac{9!}{4!(9-4)!} = \frac{9!}{4!5!} = 126 ). Thus, ( 9C4 ) equals 126.

A parallelogram is a quadrilateral .

Other quadrilaterals are

Squares, Rectangles, Rhombus, Trapezium, Kite, and irregular.

The word 'quadrilateral' means ' four sided'. 'Quad' Four and ;lateral ; sides'.

Algebraically it is

A = 0.5 X b X h

Area (A) = one half multiplied to the base length , then multiplied to the perpendicular height .

The perpendicular height is the distance , at right angles (90 degrees) from the base to the opposite point of the triangle.
