Her total bill is $186 because :
(3x39)+15+(2x27)
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad

Answer:
2. 40.83 or 13π
3. a) 6π/5
b)21.6π
Step-by-step explanation:
2. Use the proportion arc length over angle measure:
x/360 = 7.94/70
x = 360 * .113 = 40.83 or 13π in exact form
3. a) 24π/20 because circumference divided by the total number of slices which reduces to 6π/5
b) 360/20 = 18 degrees per slice, so 13 slices have an angle measure 234 degrees
Set up a proportion between the area of the full pizza over the angle measure and the area of the pizza (the unknown value being solved) and its angle measure
144π/360 = x/234
(234*144π)/360 = 21.6π
