$f-354=1221$ <em>add 354 to both sides</em>

$f+354-354=1221+354\\\\\boxed{f=1,575}\to\boxed{D.}$

Which statement about the amount of paint found by

stepan [7]

Circumference=37.68cm
2πr=37.68
6.28r=37.68
r=6cm

TSA of one hemisphere

2πr²+πr²
6.28(6)²+3.14(6)²
36(6.28)+36(3.14)
36(6.28+3.14)
36(9.42)
339.12cm³

For 2 hemisphere

TSA=2(339.12)=678.24cm³

We know that the law of sines states that:

$\frac{\sin\alpha}{a}=\frac{\sin\beta}{b}$

For simplicity, let:

$\beta=m\angle A_1BC$

In triangle A1BC this leads to:

$\begin{gathered} \frac{\sin31}{5}=\frac{\sin\beta}{6} \\ \sin\beta=\frac{6}{5}\sin31 \\ \beta=\sin^{-1}(\frac{6}{5}\sin31) \\ \beta=38.174 \end{gathered}$

Therefore:

$m\angle A_1BC=38.174$

Now, triangle A2BC is isosceles which means that both the base angles are equal, since angle CA1B and A2A1B are supplementary we have:

$m\angle CA_2B=180-38.174=141.826$
