Step-by-step explanation:
Find 2r:
11 x 11 = 121
Multiply 2r with pi:
121 x 3.141592654 = 380.1327111
= 380.13 (Nearest hundredth)
I kind of forgot my 6th grade geometry, so I'm sorry if it is wrong.
Answer:
13 and 14 po pero di ko sure
Step 1
Given;
Required; To find the difference in interest between the two periods.
Step 2
State the formula for simple interest
Step 3
Find the interest when the rate is 8%
Therefore the interest is given as;
Step 4
Find the interest in 1980 with a 20% rate
The interest is given as;
Step 5
Find the difference in interest between the two rates.
Hence, the difference in interest between the two rates = $11095.89
No, if you do something to one side you do to the other. So 3 times 4 is 12 and 5 times 4 is not 15. I hope that makes sense
