Answer:
A) false statement: B
true statement: The diameter of the circle is 12 units because a diameter is twice the radius.
B) false statement: A
true statement: The radius of the circle is 5 units because the radius is half the diameter.
Answer is D
XY = DE
-------------------
The diameter is 12 cm and the radius is alsays half of the diameter so it will be 6 cm
The volume of a cylinder is
V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:
V=40(3.14)(10^2)
V=12560 ft^3
