1) c= 3.5cm × 22/7
c= 77cm/7 = 11cm
2) c= 2×3.14×5cm
= 6.28× 5cm
=31.4cm
3) L=180/360 × 22/7 × 3cm
= 1/2 × 22/7 ×3cm
=4.71 cm
4) c=12cm ×3.14
=37.68cm
5) c = 4.5cm × 3.14
=14.13cm
6) c = 6.7cm × 3.14
= 21.038cm
I will assume monthly compound interest.
Then:
yearly interest: 12%
monthly interest = (3/12) %
invested money: C
Final money: 2C
n: number of months
Compund interest formula:
Final money = Invested money * (1 + 0.03/12)^n
2C = C * (1.0025)^n
2C/C = (1.0025)^n
2 = (1.0025)^n
n = log(2) / log (1.0025)
n = 277.6 months
Time = 278 months = 23.1 years
Answer:
10
Step-by-step explanation:
3^2*2-4(3-1)
3^2=9
9*2
9×2
18
4(3-1)
4(2)
8
18-8
=10
So the final answer is 10
