Hey there! Today I am going to share you the top 5 of some important formulae you need to learn for grade 8 exams.

1. Area of semicircle : A = 1/2πr²

2. Simple Interest: I = PRT/100

3. Compound Interest = A(Total amount) = P(1 + R/100)ⁿ

4. Total Surface Area of Prism: A = 2(Area of cross-section) + h(perimeter of cross-section)

5. Product of sum of two numbers with the difference of two numbers: (a + b)(a – b) = a² – b²
