Here are the formulas matched to each topic listed:
-
Volume - C. \( V = B * h \), where \( B \) is the area of the base.
-
Surface Area - E. \( A = \text{add up area of all faces/surfaces} \).
-
Permutation - F. \( \frac{n!}{(n-r)!} \).
-
Combination - A. \( \frac{n!}{r! \cdot (n-r)!} \).
-
Area of Rectangle - D. \( A = b * h \), where \( b \) is the length of the base.
-
Area of Circle - B. \( A = \pi r^2 \).
-
Area of Triangle - G. \( A = \frac{1}{2} b * h \), where \( b \) is the length of the base.
