Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project.in feet how much board was left?
guapka [62]

\frac{5}{8} \text{ feet board is left }

<em><u>Solution:</u></em>

Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project

To find: Board that was left

From given,

\text{Total length of board } =\frac{7}{8} \text{ feet }

\text{Foot that was cut off } = \frac{1}{4} \text{ feet }

Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

\text{Reamining board } = \text{Total length of board - feet of board that was cut off}\\

Substituting the values we get,

\text{Remaining board } = \frac{7}{8} - \frac{1}{4}\\\\\text{Remaining board } =\frac{7}{8} - \frac{1 \times 2}{4 \times 2}\\\\\text{Remaining board } =\frac{7}{8} -\frac{2}{8} = \frac{7-2}{8}\\\\\text{Remaining board } =\frac{5}{8}

Thus \frac{5}{8} feet board is left

Daniela is a stain glass artist; she created the window below for her living room. What is
OLga [1]
The window has a shape of a semi-circle (half of a circle).

We know the diameter d = 12 ft.

The area of a (complete) circle is given by the formula:
A = π × r²

The radius can be found by halving the diameter:
r = d ÷ 2
  = 12 ÷ 2
  = 6 ft

Therefore the area of the circle will be:
<span>A = π × r²
    = 3.14 × 6</span>²
    = <span>3.14 × 36
    = 113.04 ft²

And the area of the semi-circle:
A = </span><span>113.04 </span>÷ 2
   = 56.52 ft²

Hence, the area of the window will be 56.52 ft².
