AveGali [126]

Answer:

$lets \: \: find \: \: \: the \: \: \: radius \\ 2\pi \: r = 132 \\ \frac{2\pi \: r}{2\pi} = \frac{132}{2\pi} \\ r = 21.01$

$lets \: \: \: find \: \: \: the \:area \: now \\ = \pi {r}^{2} \\ = \pi \times {21.01}^{2} \\ = 1,386.76$

$lets \: fin d\: \: \: the \: \: diameter \\ = d = 2r \\ = d = 2 \times 21.01 \\ = d = 42.02$

Answer:

x = 76.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side / adj side

tan 70 = x/28

28 tan 70 = x

x=76.92936

Rounding to the nearest tenth

x = 76.9
