Answer:

$14.12 (after 3 years) and $24.62 (after 5 years)

Step-by-step explanation:

Use the compound amount formula (assuming annual compounding):

A = P(1 + r)^t

Here A = $100(1 + 0.045)^3 (after 3 years)

= $100(1.045)^3 = $114.12.

The interest earned (alone) would be $14.12.

After 5 years:

Here A = $100(1 + 0.045)^5 (after 5 years)

= $100(1.045)^5 = $124.62

The interest earned (alone) would be $24.62.

emmasim [6.3K]

Answer: The area of the regions covered by grass is approximately 313.375 sq ft.

Step-by-step explanation:

Given: A company is building a new park in the shape of a circle with a 25 ft diameter.

Then radius = $\dfrac{25}{2}=12.5\ ft$

Required area = Area of circle - Area of rectangle + Area of triangle

Formula: Area of circle = $\pi r^2$

Area of rectangle = length x width

Area of triangle = 0.5 x base x height

Area of circle = $(3.14)(12.5)^2=490.625\ \text{ft}^2$

Area of rectangle = 20 ft x 10ft = 200 ft²

Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²

Required area = 490.625 -200+22.75 = 313.375 ft²

Hence, The area of the regions covered by grass is approximately 313.375 sq ft.
