Becuase 80 is the same as 8 but has an extra 0 at the end (which makes it 80) and same for 20 to 2. 8 + 2 = 10 (now add a zero at the end). The answer should be 100.
Cicumference = Dπ or 2rπ
thus if r = 2.2
then C = 2 (2.2)π
= 4.4π
D is the answer
Answer:
x=20
Step-by-step explanation:
x=20 because 4×20=80
and 80-20= 60
Answer:
x = 3 and y = 3
Step-by-step explanation:
4 times 3 is 12. 2 times 3 is 6
12 minus 6 is 6
Given:
Principal = ₹ 5000
Compound rate of interest = 6% per annum
Time = 3 years
To find:
The amount after 3 years of compound interest.
Solution:
Formula for amount is:

Where, P is principal, r is rate of interest in % and t is the number of years.
Putting P=5000, r=6 and t=3, we get



On further simplification, we get



Therefore, the amount after 3 years of compound interest is 5955.08.
