Hello there!

Since you already know that for each pound of candy Josephine buys, she has to pay 14.95 dollars, you can use this to find how much she must pay if she buys 0.63 pounds of candy.

To solve this, you must multiply 14.95 and 0.63.
This would be represented by this expression:
14.95*0.63

When you simplify, you should get 9.4185.

However, the problem asks to round to the nearest cent, which would be the hundredths place. When you round 9.4185 to the nearest cent, you should get 9.42.

Therefore, Josephine pays $9.42 dollars for 0.63 pounds of candy.

A semicircle is drawn onto one of the shorter sides of a rectangle. The shorter side of the rectangle measures 4 centimeters. Th

<h3>Answer:</h3>

8.78 cm

<h3>Solution:</h3>

We are given that :

A semicircle is drawn onto the shorter side of rectangle.
Shorter side of rectangle measures 4cm. i.e; the diameter of the circle is 4cm
Area of the figure is 41.4 cm²

Using Formulas:

Area of rectangle:

$\quad\hookrightarrow\quad{\pmb{ \mathfrak {length\times breadth }}}$

Area of semicircle:

$\quad\hookrightarrow\quad{\pmb{ \mathfrak{ \dfrac{\pi r^2 }{2}}}}$

We have to find the length of longer side of rectangle!

Here, we can know that the figure is composed of one rectangle and one semicircle. Therefore by combining the areas of rectangle and circle and taking the length of rectangle as a variable , we will finds its value ;

$\quad\dashrightarrow\quad \sf {Area_{\tiny { total}} = Area_{\tiny {rectangle}}+ Area_{\tiny {semicircle}}}$
