Find the interest on naira 40000.00 for 2 years at 20% per annum compound interest. Please I need the answer ASAP

andrey2020 [161]

Given:

Principal value = 40000

Rate of compounded interest = 20%

Time = 2 years

To find:

The interest.

Solution:

Formula for amount is

$A=P\left(1+\dfrac{r}{100}\right)^t$

Where, P is principal, r is rate of interest and t is time in years.

Putting the given values, we get

$A=40000\left(1+\dfrac{20}{100}\right)^2$

$A=40000\left(1+\dfrac{1}{5}\right)^2$

$A=40000\left(\dfrac{6}{5}\right)^2$

$A=40000\left(\dfrac{36}{25}\right)$

$A=57600$

Now, the formula for interest is

$I=A-P$

$I=57600-40000$

$I=17600$

Therefore, the amount of compound interest is 17,600.

The surface area of three dimonsensed face is the sum of all the the surface areas of each of the face given below are the nets

Ann [662]

Answer:

cylinder:

curved sa = 2πrh

=> rectangle, breath = h, width = perimeter of circle = 2πr

total sa = 2πrh+2πr^2

=> curved sa + area of 2 circles

cone:

curved sa = πrl

=> treated as a triangle, base = circumference of circle, height = slant height

total sa = πr^2+πrl

=> curved sa + area of base (circle)
