A = pi × r²
3.14 x 2²
3.14 x 4
A = 12.56636 ≈ 12.56
hopefully this helps u and if u know the formula to solve it, it is super easy
Answer:
The simple interest for 4 months = Rs 240
Step-by-step explanation:
formula:-
simple interest I = [PNR]/100
P - Principle amount
N - Number of years
R - Rate of interest
It is given that, $7,800 at 9.25% for 4 months
<u>To find the simple interest for 1 year</u>
I = [PNR]/100
I = [7800*1*9.25]/100 = 721.5
<u>To find the simple interest for 4 months</u>
4 months = (1 year )/3
4 months interest = 721.5/3 =240.5 ≈ 240
Therefore the simple interest for 4 months = Rs 240
