Answer:
x = 4
Step-by-step explanation:
as it is parallelogram opposite sides are equal
so14x -7= 10x-9
14x-7+9=10x
14x -16 = 10x
14x -10x = 16
4x =16
x = 16/4
x = 4
also u can put x = 4 in both expressions and u will get answer of both 49
The formula for the volume of a cone is
v = ( 1 / 3) h pi r^2
where h is the height of the cone
pi is 3.1416
r is the radius of the cone
since diameter is given
D = 2r
r = D/2 = 4/2 = 2 in
substitute the given
V = (1/3) (6) (3.1416) (2^2)
V = 25.1 cubic in
Answer:
For the triangle, the area is 7.5 in.
For the trapezoid, the area should be 90 cm
Step-by-step explanation:
The formula for a triangle is A=1/2bh and for a trapezoid it is (a+b)/2×h
