Answer:
49π or 153.938 mm²
Step-by-step explanation:
Area of a Circle Formula: A = πr²
Since we are given radius <em>r</em>, simply plug it into the formula:
A = π(7)²
A = 49π
A = 153.938
4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
Answer:
First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.
Step-by-step explanation:
No the triangle has no right angles
Answer:
You will earn $483.55 in interest.
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
$3,000 T - note with a 3% annual rate
This means that
Paid quarterly
Quarterly is 4 times per year, so
Maturity in 5 years.
This means that
How much interest will you earn?
Interest is the final amount subtracted by the principal.
Final amount:
A(5).
Interest:
$3,483.55 - $3,000 = $483.55
You will earn $483.55 in interest.
