Daniela is a stain glass artist; she created the window below for her living room. What is
1 answer:
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.

Hope this helps!!
I used the variable n as the number we needed to find. The equation was n + 8 + 12 = 3n
I believe 4 people would get 7.5 part of of it
D because those options do not intersect and are part of the universal set
Answer:
A) perimeter = 3 + 3 + 8 + 8 = 22 units
B) area = 3 x 8 = 24 units²
