Answer:
68.1 units²
Step-by-step explanation:
Start by finding the area of the rectangle...

Then, find the area of the semicircle...


Now, add the two to get...
54+14.1=68.1
For this case we have the following equation:
s = 300 / d
Where,
s: the speed of the current in a certain whirlpool
d: the distance from the center of the whirlpool
We have then that:
If the distance from the center of the whirpool is large, the speed is small.
If the distance from the center of the whirlpool is very small, the speed tends to infinity
Answer:
Large distance, small speed.
Short distance, speed tends to infinity.

Given:
Principal = $1400
Simple rate of interest = 1.25%
Time = 6 month
To find:
The balance of the account after simple interest.
Solution:
The formula for simple interest is

Where, P is principal, r is the rate of interest in % and t is time in years.
Time = 6 months
=
year
= 0.5 year
Putting 1400, r=1.25, t=0.5 years.



Now, the amount is



Therefore, the balance of the account after the simple interest is $1408.75.
