Question

what is the formula of 2 and 3 pls tell​

Answer 1

Answer:

1. The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.
2. Simple interest is calculated by multiplying the daily interest rate by the principal, by the number of days that elapse between payments. Simple interest benefits consumers who pay their loans on time or early each month.

Answer 2

2. The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius. The perimeter of Semicircle = (1/2) π d + d or (πr + 2r)

3. Formula of simple interest = S.I = P x R xT / 100

where,

P = Principle

R = Rate of Interest

T = Time period
