A circle with radius 2 sits inside a 7×11 rectangle. What is the area of the shaded region?

We draw the problem in the picture attached. The picture is not drawn to scale!

In order to find the shaded area, you need to subtract the area of the circle from the area of the rectangle.

Therefore:
A(rectangle) = b·h = 11×7 
                               = 77 u²

A(circle) = π·r² = 3.14 · 2²
                        = 3.14 · 4
                        = 12.56 u²

A(shaded) = A(rectangle) - <span>A(circle) 
                  = 77 - 12.56
                  = 64.44 u²

Hence, the shaded figure has an area of 64.44 square units.

Art [367]

Answer:

The money was left untouched for 2 years and 6 months or just 2.5 years

Step-by-step explanation:

In this question, we are asked to calculate the time taken for an amount deposited to earn a certain amount of interest.

Mathematically, simple interest can be calculated using the formula;

I = PRT/100

where I is the interest accrued which is 3696.88 - 3,500 = 196.88

P is the principal which is the amount deposited = 3,500 according to the question

R is the rate which is 2.25% according to the question

T is the time which we are to find

we can rearrange the formula making T the subject and we obtain the following;

T = 100I/PR

substituting the values listed above we have;

T = (100 * 196.88)/(3500 * 2.25)

T = 19688/7875

T = 2.5 years or 2 years 6 months
