Answer:
38 Tables
Step-by-step explanation:
182 + 274 = 456
456 / 12 = 38
<span>If x= side of the square, and A = area of square, then
A = x^2
dA/dx = 2x, or
dA = 2x*dx, where dx is the differential in x (same as error)
dA/A = 2x*dx/(x^2) = 2*dx/x = 2*(0.05cm)/(15cm) = 0.00667 = 0.667%
for b):
if dA/A = 0.025 = 2*dx/x, then
dx/x=(0.025)/2 = 0.0125 = 1.25 %

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
