Answer:1695.6 square inche
Step-by-step explanation:
radius=r=6
Height=h=15
π=3.14
Volume =π x r^2 x h
Volume =3.14 x 6^2 x 15
Volume =3.14 x 36 x15
Volume =1695.6 square inches
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
Check the picture below.
thus, the radius of each is 4 inches, and the heights are 9 and "h" respectively.
the volume of the figure is the volume of the cone plus the volume of the cylinder then, thus
