Formula to find the central angle is,

Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and
.
First step is to plug in these values in the above formula. So,

By simplifying.
Since 

s=14.65
Hence, arc length iss 14.65 feet.
Answer:
12083.3314
Step-by-step explanation:
5*5*5= 125
125/3=41.66666
41.66666*290= 12083.3314

We know that
if t<span>he temperature T of a given mass of gas varies inversely with its volume V
</span>then
T=k/V
Step 1
Find the value of k
for T=30º C and V=105 cm³
we have
T=k/V--------> k=T*V--------> k=30*105=3150 °C*cm³
therefore
for V=84 cm³
T=3150/84=37.5 °C
the answer is 37.5 °C
