Answer 1

Answer: you have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right

Answer 2

Answer: a) We know that the radius of the top of the window is two side lengths of a square. Since each square has a side length of 10 inches, the radius of the half-circle portion is 20 inches. The area of a half-circle is (pi*r²)/2 (r being radius and pi being 3.14). There are 16 squares as well. So the equation is ((3.14*20²)/2) + (16*100)=2,228 in²
b) The next part's a little tricky, but just add 4 inches to the radius and 4 inches to all of the affected outer-rim squares. You should get 3016.32 in²

What is simple interest?

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.

Simple Interest = (Principal × Rate × Time) / 100

Given;

P = $350

r = 0.03

t = 10 years

The interest earned;

I =I = P × r × t

I =350 × 0.03 ×10

I = $105

Therefore, the interest earned will be $105
