Its prolly B becuz i think u square the answer
Answer:
10 miles is answer because u should divide d=r
Equation: <span>5/7d=2/3
Work:
5d/7 = 2/3
5d = 2/3 x 7
5d = 14/3
d = 14/3/5
d = 14 / 3 x 5
d = 14/15
Final Answer:
14/15 or 0.933333

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.
