Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m
Answer:
D
Step-by-step explanation:
you find the radius by using the diameter
hence radius = diameter divide by 2 which is 1÷2 which is 0.5
next step the volume of the cylinder is πr^ 2h
22÷7 × 0.5×0.5×8 gives you 6.2857 to 5 significant number
There isn't enough information to answer this, what is the given area or perimeter?
0 solution
3(x+4)=3x+4
3x+12=3x+4
(3x-3x)=(-12+4)
0=-8
so no posible solution
I believe it is the second option
