<h3>The monthly payment is $242.44 for loan to paid off in 3 years.</h3>
Step-by-step explanation:
The amount borrowed = Principal = $8000
The rate of interest = 7.2%
Time (T) = 3 years
Now, Simple Interest =
So, the total interest = $1728
Now, <u>Amount to be paid = Principal + Interest</u>
⇒ A = $8000 + $1728 = $8728
Also, 1 year = 12 months
⇒ 3 years = 3 x 12 months = 36 months
So, total amount to be paid in 36 months is $8728.
⇒The amount to be paid in 1 month is
Hence, the monthly payment is $242.44 if loan is to paid off in 3 years.
Given that, a sphere has a surface area of about 999 square millimeters.
Formula to find the surface area of sphere is,
S= 4πr² Where r = radius of the sphere and S= surface area.
Given S= 999 square millimeters.
So, we can write:
4πr² = 999
4 * 3.14 * r² = 999 Since, π = 3.14
12.56 *r² = 999
Divide each sides by 12.56.
r² = 79.53821656
r = √79.53821656 Taking square root to each sides of equation.
r = 8.918420071
So, r = 8.918 Rounded to nearest thousandth.
So, radius of the sphere is 8.918 millimeters.
Hope this helps you!
