$EF=15.4\ ft$

Step-by-step explanation:

we know that

In the right triangle DEF

$tan(E)=\frac{FD}{EF}$ ----> by TOA (opposite side divided by adjacent side)

substitute the given values

$tan(32^o)=\frac{9.6}{EF}$

solve for EF

$EF=\frac{9.6}{tan(32^o)}=15.4\ ft$

31.4 in^2

Explanation:

The Formula for finding circumference is π*d (d=Diameter) or in this case 3.14*d. all you have to do is plug in 10 into the formula and get 3.14*10= 31.4 in^2
