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
V=(1/4)³
V=1/16 ft³
volume of 4 cubes= (1/16)·4=4/16= 1/4 ft³
Answer:
-x - 12 + 3y
Step by step explanation:
-2x + 10 - (6 + 5y) + x + 8y - 16
-2x + 10 - 6 - 5y + x + 8y -16
-x - 12 + 3y
