Answer:
Step-by-step explanation:
sin²β + sin²β×tan²β = tan²β
sin²β( 1 + tan²β ) = tan²β
~~~~~~~~~~~~~~~~
<u><em>sin²β + cos²β = 1 </em></u>
<u><em /></u>
+
=
⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β
~~~~~~~~~~~~~~
1 + tan²β =
L.H. = sin²β (
) = tan²β
R.H. = tan²β

We are given radius = 6 yards
area of circle = pi * r * r = 3.14 * 6*6 = 113.04 yard square
cost of carpet is $14 per square yard
cost of 113.04 square yard = 14*113.04= 1582.56 dollars
Answer: cost to carpet the planetarium is $1582.56
