Volume equals pi times r squared times height
So it would be 81pi in cubed
(a) Find the value of x.
Sum of interior in a triangle = 180
So m<BAC + m<ABC + m<BCA = 180
4x + 10 + 5x + 18 + 3x - 16 = 180
12x + 12 = 180
12x = 168
x = 14
(b) Find the measure of <3.
<3 + <BCA = 180
<BCA = 3x - 16 = 3(14) - 16 = 26°
So
<3 = 180 - <BCA
<3 = 180 - 26
<3 = 154°
distance = speed * time
the first bus speed = x
second bus = x - 12
the sum of distance = 765 miles
first distance = 6x
second distance = 6 (x -12)
6x + 6(x-12) = 765
x + x -12 = 127.5
2x = 139.5
x = 69.75 mi/h which is the faster bus
the second bus speed = 57.75 mi/h
5*2=10
10+12*4.5=64cm^2
Hope it helps
