• Reflection in x-axis

• Reflection in y-axis

Area of circle

• $\ \pi r^2$

• $2\pi r$

• $\pi d$

• $\frac{d}{2}$

Area of an equilateral triangle

•  $\frac{1}{2}bh$  

•  $\frac{\sqrt{3}}{4}^{ }a^2$  

•  $l\times b$  

•  $2\left(l+b\right)$  

This is the net of tetrahedron

 $What\ can\ be\ found\ from\ this\ formula,\ \frac{PTR}{100}=I$  

• Interest

• Interest and Time

• Interest, Time and Rate of Interest

• Principal, Interest, Time and Rate of Interest

Profit (P)=

• C P - S P

• S P - C P

• C P + S P

• S P + CP

 $P\%\ =$  

•  $\frac{P}{SP}\times100\%$  

•  $\frac{P}{CP}\times100\%$  

•  $\frac{CP}{SP}\times100\%$  

•  $\frac{SP}{CP}\times100\%$  

If SP and P% are given then formula to find CP is

•  $SP=\frac{CP\times100}{100+P\%}$  

•  $CP\ =\frac{SP\times100}{100+P\%}$  

• CP = SP-P

• CP = SP+L
