A rose garden Is formed by jolning a rectangle and a semicircle, as shown below. The rectangle Is 23 ft long and 14 ft wide.Find
Ratling [72]

Answer:

Area of the garden:

\begin{equation*} 398.93\text{ ft}^2 \end{equation*}

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;

r=\frac{d}{2}=\frac{14}{2}=7\text{ ft}

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

A_{sc}=\frac{\pi r^2}{2}=\frac{3.14*\left(7\right)^2}{2}=\frac{3.14*49}{2}=\frac{153.86}{2}=76.93\text{ ft}^2

Let's also determine the area of the rectangle;

A_r=l*w=23*14=322\text{ ft}^2

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

\begin{gathered} Area\text{ of the garden = Area of semi circle + Area of rectangle } \\ =76.93+322 \\ =398.93\text{ ft}^2 \end{gathered}

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

An angle measures 51 degrees. Through what fraction of a circle does the angle turn? (Try the Math Quill using Delimiters to typ
adell [148]

Answer:

\frac{17}{120}

Step-by-step explanation:

Given: An angle measures 51 degrees

To find: fraction of a circle by which the angle turn

Solution:

Angle at the centre in a circle is equal to one complete angle i.e., 360^{\circ}

Measure of an angle =51^{\circ}

Therefore,

Fraction of a circle by which the angle turn = Measure of an angle/ Angle at the centre in a circle \frac{51^{\circ}}{360^{\circ}}=\frac{17}{120}
