Answer:
Area of the garden:

Explanation:
Given the below parameters;
Length of the rectangle(l) = 23 ft
Width of the rectangle(w) = 14 ft
Value of pi = 3.14
Since the width of the rectangle is 14 ft, so the diameter(d) of the semicircle is also 14 ft.
The radius(r) of the semicircle will now be;

Let's now go ahead and determine the area of the semicircle using the below formula;

Let's also determine the area of the rectangle;

We can now determine the area of the garden by adding the area of the semicircle and that of the rectangle together;

Therefore, the area of the garden is 398.93 ft^2

Step-by-step explanation:i dont know
6.9 x 10⁷ is a scientific notation.
6.9 x 10⁷ in standard form is 69,000,000
Scientific notation is used to represent very large numbers or very small numbers.
Scientific notation has three parts. Its parts are the coefficient, base of ten, and the exponents.
6.9 is the coefficient
10 is the base of 10
7 is the exponent
The must always be 1 digit before the decimal point in the scientific notation.
The exponent tells us the number of places the decimal point has moved. Its sign tells us the direction of the decimal point's movement.
Since the exponent is positive, it tells us that the decimal point moved from right to left.
69000000. to 6.9000000
If the exponent had a negative sign, it means that the decimal point moved from left to right.
example: 6.9 x 10⁻⁷
its standard form would have been .00000069
