Answer:
Step-by-step explanation:
perimeter of the figure = perimeter of the rectangle + perimeter of the semicircle
= 2(l+B) +
r
= 2( 10+8) + 3.14 × 5
= 36 + 15.7
= 51.7
= 100 ( rounding off to nearest hundredth )

Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h

solution:
solid spindle ab:
c= 1/2ds = ½(1.5) = 0.75in.
j= π/2c1= π/2(0.75)2 = 0.49701 in4
jmax = Tc/j
tab=jtal/c = (0.49701)(12)/0.75 = 7.952
sleeve cd = c2 = 1/2d2 = ½(3.0) = 1.5in
j = π/2(c24 – c14) = π/2(1.54-1.254) = 4.1172 in4
tab = jtl/c2 = (4.1172)(7)/1.5 = 19.213 kip.in
