Answer:

Step-by-step explanation:

1: Base Surface Area = π×72

= 153.9380400259 millimeters2

Lateral Surface Area = π×7×√72 + 142

= 344.215921821 millimeters2

Total Surface Area = 498.1539618469 millimeters2

Rounded = 500 millimeters2

2:Base Surface Area = π×52

= 78.539816339745 centimeters2

Lateral Surface Area = π×5×√52 + 102

= 175.62036827602 centimeters2

Total Surface Area = 254.16018461576 centimeters2

Rounded 300 centimeters2

Answer:

The amount becomes $6964.53 after 3 years .

Step-by-step explanation:

Formula

$Amount = P (1+\frac{r}{4})^{4t}$

Where P is the principle , r is the rate of interest in the decimal form and t is the time in the years .

As given

Earl invested 6,000 in a money market account that pays 5% interest quarterly for 3 years .

P = $6000

5% is written in the decimal form.

$= \frac{5}{100}$

= 0.05

r = 0.05

t = 3 years

Putting all the values in the formula

$Amount = 6000(1+\frac{0.05}{4})^{4\times 3}$

$Amount = 6000(1+0.0125)^{12}$

$Amount = 6000\times 1.16075452$

$Amount =\$ 6964.53\ (Approx)$

Therefore the amount becomes $6964.53 after 3 years .
