Step-by-step explanation:
2 bases 3 rectangles, folds properly.
the volume of the composite figure is . Correct option D)
<u>Step-by-step explanation:</u>
Here we have , The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 5 mm. We need to find What is the volume of the composite figure . Let's find out:
We know that Volume of figure is :
⇒ Volume of cylinder + Volume of hemi-sphere
⇒
⇒
Putting values of h= 10 mm , r = 5 mm( Not given in question ! Searched in correct question )
⇒
⇒
⇒
Therefore , the volume of the composite figure is . Correct option D)
If cos(70) = 0.342
the cosine of the alternative angle of 70° will also give the same value
angle measure = 360 - 70 = 240°
cos (240) will also be 0.342
Answer:
b = -18
Step-by-step explanation:
(3 + 4i) (-3-2i)
When we foil:
-9 + -6i + -12i + -8i^2
-8i^2 = +8
Combine like terms:
-1 + -18i
