Mr. lira opened an account with a deposit of $2,000.

NNADVOKAT [17]

Answer:

A) 25%

Step-by-step explanation:

Simple interest rate = $3,500

Principal, p = $2,000

Time, t = 7 years

Rate, r = ?

Simple interest rate = (principal × rate × time) / 100

3,500 = (2,000 × r × 7) / 100

3,500 * 100 = 14,000r

350,000 = 14,000r

r = 350,000/14,000

r = 25%

3. Your new job requires you to calculate the material

The area of the circular manufactured good is given by:

$A = 1.8146 \times 10^{16} \text{m}^2$

<h3>What is the area of a circle?</h3>

The area of a circle of radius r is:

$A = \pi r^2$ .

In this problem, the radius in meters is:

$r = 7.6 \times 10^7$

Hence the area in m² is:

$A = \pi (7.6 \times 10^7)^2 = 181.46 \times 10^{14} = 1.8146 \times 10^{16} \text{m}^2$
