Answer:
Can someone translate that sentence please?
Step-by-step explanation:
height,h = 3"
base, b = length, l = 2
area of triangle, t = bxh/2...eqn 1
area of square, s = l^2...eqn 2
area of pyramid, p =4t + s...eqn 3
subst h = 3 and b = 2 in eqn 1
t = 3x2/2 = 3
subst l =2 in eqn 2
s = 2^2 = 4
subst t = 3 & s = 4 in eqn 3
p = 4(3) + 4 = 16sq inch
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.
