Answer 1

Answer:

what is the formula for mean and median, square, and rectangle and sphere

Answer 2

Answer:

MEAN:

$\frac{sum \: of \: the \: terms \: }{number \: of \: the \: terms}$

MEDIAN:

$\frac{n + 1}{2} if \: n \: is \: odd \\ \\ \frac{n}{2} \: if \: n \: is \: even$

SQUARE:

AREA = SIDE^2

PERIMETER =4×SIDE.

DIAGONAL=

$\sqrt{2a}$

RECTANGLE:

AREA=L×B

PERIMETER =2(L+B)

DIAGONAL =

$\sqrt{l \times b}$

SPHERE=

VOLUME:

$\frac{4}{3}\pi {r}^{3}$

DIAMETER =2 R

SURFACE AREA:

$4\pi {r}^{2}$
