Billy invests £800 for 5 years in a savings account. By the end of the 5 years he has received a total of £96 simple interest.

Work out the annual rate of simple interest?

24%

Step-by-step explanation:

First solve:

800*5 = 4,000

Then:

96 divided by 4,000 = 0.024

0.024 in percent = 24%

Thus, 24% will be your answer

2.4%

Step-by-step explanation:

800×5=4000

96÷4000=0.024

0.024×100=2.4%

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
