Firstly, find the radius with the formula diameter (d) : 2
8 : 2 = 4 cm
The Vilume formula is r²hπ = 4²*12*π = 16*12*π = 192π cm³
Your exercise says to use "3" as a value for π
Then V is 192*3 = 576 cm³
Answer:
the answer is 31
Step-by-step explanation:
When two straight lines cut each other vertical angles are formed. There are two pair of vertical angles .Vertical opposite angles are always equal .
In the figure Substituting the values of the angles given.
x+40=3x.
Subtracting x both sides.
40=3x-x
40=2x. Dividing both sides by 2.
X=20.
Answer:
4
Step-by-step explanation:
13 - 5 = 8
2 x 4 = 8
8 + 5 = 13
(5-12)^2+8/(-2)
(-7)^2+8/(-2)
(49)+8/(-2)
(49)+(-4)
45
Using PEMDAS, your answer would be 45.
