Answer:
Step-by-step explanation:
for nr. 1
sum of angles in a triangle=180
x=180-(81+84)=15
acute triangle
for nr.2
x=180-(24+36)=120
obtuse triangle
X = multiplication
h = height
r^2 = radius squared
Formula of a cylinder: Pi x r^2 x height
So, if 176 = 3.14... times 4^2 times h
Then, 176 = 3.14 times 16h
Next, 176 = 50.24h
Finally, 3.5 = h
You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.
Answer:
.66 cu. meters
Step-by-step explanation:
volume for cone is V=1/3 x TT x r^2 x height
TT (pi) is 3.14
radius is 1/2 of diameter (1/2 x 1.5 = .75 )
height is 1.5 x radius (1.5 x .75 = 1.125)
V= 1/3 x 3.14 x .75^2 x 1.125
V= .66 cu. meters
