Answer:
6
Step-by-step explanation:
48 divided by 8 is 6
Answer:
Step-by-step explanation:
radius of circle=4
diameter=4×2=8
width=2 half circles means diameter=8
length=2 diameters=2×8=16
area=16×8=128
4 half circles make two circles
area of two circles=2×π r^2=2×π×4²=32 π
reqd . area=128-32 π=32(4-π)
Answer:
12.02 inches
Step-by-step explanation:
recall, volume of a cylinder is given by
V = πr²h
where r is the radius of the cylinder and h = the height
hence
9080 = π x r² x 20
r² = 9080 ÷ 20π = 144.513
r = √144.513 = 12.02 inches
Answer:
Step-by-step explanation:
Answer:
B. 3x^2 - 2x - 1.
Step-by-step explanation:
(f + g)x = f(x) + g(x)
= -4x + 3 + 3x^2 + 2x - 4
Adding like terms we get the answer:
= 3x^2 - 2x - 1.
