Can you please answer this

jasenka [17]

Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°

Find the volume and surface area of the composite figure. Give four answer in terms of π. HELP NEEDED NOW!!! THE RED IS THE ONE

asambeis [7]

Answer:

Divide the figure above into a cylinder and a dome

+) the volume of the dome is

$v1 = \frac{1}{12} \pi6 {}^{3} = 18\pi$

the surface area is

$s1 = \pi3 {}^{2} = 9\pi$

+) the volume of the cylinder is

$v2 = \pi.3 {}^{2} .13 = 117\pi$

the surface area is

$s2 = 2\pi.3.13 + 2\pi.3 {}^{2} = 96\pi$

so the volume of this figure is

$v = v1 + v2 = 18\pi + 117\pi = 135\pi$

the surface area of this figure is

$s = 9\pi + 96\pi = 105\pi$
