The formula for the area of a circle is a = <span>πr², r being the radius.
To tackle this problem, find the area of the square and then subtract the area if the circle:
Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314
Area of square - area of circle = 400 - 314 = 86 m²
Hope this helps!

0.8 is greater because 3/4 equals .75
Answer:
The correct answer is option B.
m<3 = m<6
Step-by-step explanation:
From the figure we an see that, a and b are parallel lines and line t is the traversal on the lines.
<u>To find the correct option</u>
From the given figure we get
Corresponding angles are,
<1 & <5, <2&<6, <2&<7 and <4 &<8
Alternate interior angles are,
<3 & <6 and <4 &<5
Alternate interior angles are equal.
m<3 = m<6
Therefore the correct answer is optionB
Answer:
80 ft x 40 ft
Step-by-step explanation:
Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).
The equations that compose the linear system are:

Solving the system:

The garden is a rectangle with dimensions 80 ft x 40 ft.
