Answer:
subs 3 and 4 into the equation and then compare the two equation to get the value of two constants p n q
First you need to calculate the circumference of the circle:
Circumference = diameter x PI = 16 x PI = 16 * 3.14 = 50.24
The intercepted arc is 15 degrees.
To find the length multiply the circumference by the central angle divided by 360.
Arc length = 50.25 x (15/360) = 2.1 units.

Answer:
37.7 ft²
Step-by-step explanation:
2×3.14×r=30.77
<em>Divide both sides by 2</em>
3.14×r=15.385
<em>Divide both sides by 3.14</em>
r≈4.9
3.14×r²
3.14×4.9²=
24.01×3.14≈
75.4
75.4÷2=
37.7
