Answer:
D
Step-by-step explanation:
yes it is found by multiplying phi with diameter of the circle
Are the first numbers ratios?
Product = multiply
(6x-y)*(2x-y+2) =
12x^2 -8xy + 12x + y^2 - 2y
Answer:
A = π · (r²)
Step-by-step explanation:
π · r² is the area of a circle.
While π · r² · h can also give you the radius, it can only do so for the Volume 
, not the Area 
.
doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.
π · r³ seems awfully like the volume of a sphere, but there's something missing. The true volume of a sphere is 
· π · r³, not π · r³.
only applies for triangles.
