Question | Answer |
Perimeter of a rectangle | P = 2L + 2W or P = 2(L + W) |
Circumference of a circle | C = 2*π*R or C = π*D |
Area of a rectangle | A = L*W or A = B*H |
Area of a triangle | A = ½*B*H or A = (B*H)/2 |
Area of a trapezoid | A = ½*(B1 + B2)*H or A = ((B1 + B2)*H)/2 |
Area of a regular polygon | A = ½*a*P [P = perimeter of the Base of a 3-D figure] |
Area of a circle | A = π*R² |
Surface area of a cube (total) | S = 6s² |
Surface area of a prism (lateral) | S = P*H |
Surface area of a prism (total) | S = P*H + 2B |
Surface area of a pyramid (lateral) | S = ½P*L |
Surface area of a pyramid (total) | S = ½P*L + B |
Surface area of a cylinder (lateral) | S = 2π*R*H |
Surface area of a cylinder (total) | S = 2π*R*H + 2π*R² or S = 2π*R(H + R) |
Surface area of a cone (lateral) | S = π*R*L |
Surface area of a cone(total) | S = π*R*L + π*R² |
Surface area of a sphere | S = 4π*R² |
Volume of a prism or cylinder | V = B*H |
Volume of a pyramid or cone | V = 1/3(B*H) |
Volume of a sphere | V = 4/3(π*R³) |
Pythagorean Theorem | a² + b² = c² |
Distance Formula | D = √(xsub2 -xsub1)² + (ysub2 - ysub1)² |
