h = 4.2 ft
<em><u>Fraction</u></em><em><u>:</u></em>
ft
Step-by-step explanation:
<u><em>Cross multiply.</em></u>
h · 15 = 9 · 7
<u><em>Simplify.</em></u>
15h = 63

h = 4.2
Answer:
28.2743 square feet (28 square feet, rounded)
Step-by-step explanation:
The area of a circle is given by the equation
Area = πr^2
Plug in 3 for the radius
Area= π(3)^2
3 squared is 9
Area= 9 π
Area= 28.2743 square feet
Rounded to the nearest square foot, the area of the circle is 28 square feet.
68+70=180
=138=180
=180-138
=42 degrees (using angle sum property of triangles
Hope this helps you
