Answer:
option 2nd is correct
volume of a cone is, 10.75 cubic inches
Step-by-step explanation:
Volume of a cone (V) is given by:
......[1]
where,
r is the radius of the cone and h is the height of the cone respectively.
As per the statement:
The volume of a cylinder is 32.25 cubic inches.
Volume of a cylinder is given by:
⇒
Divide both side by 3.14 we have;
It is also given that a cone has the same height and radius as the cylinder.
⇒ and
⇒
Using formula [1] we have;
Simplify:
cubic inches
therefore, volume of a cone is, 10.75 cubic inches
Answer:
∠1 =109
∠2= 71
Step-by-step explanation:
if they are a linear pair that means they must both (when added together) equal 180 degrees, so this means we can add them and set them equal to 180!
8x+20=180
8x=160
x=20
then we just input them!
m∠1 = 5(20) + 9 = 109
m∠2 = 3(20) + 11 = 71
