Answer:
Volume of the rolling pin = 246.09
Step-by-step explanation:
Length of larger cylinder L = 12 in
Diameter of larger cylinder D = 5 in
Diameter of two handles = 1.5 in
Length of two handles = 3 in
Volume of the rolling pin = Volume of two handles + Volume of larger cylinder
Volume of two handles = 2 ()
Volume of two handles = 2 (3.14 × × 3 )
Volume of two handles = 10.59
Volume of larger cylinder = ()
Volume of larger cylinder = (3.14 × × 12 )
Volume of larger cylinder = 235.5
Volume of the rolling pin = 10.59 + 235.5
Volume of the rolling pin = 246.09
From the chord theorem we know that:
so:
Answer C.
<u> case a)</u> The area of the square hole is 8 square centimeters
we know that
the area of a square is equal to
where
b is the length side of the square
in this problem we have
<u>Find the length side b</u>
<u>the answer Part a) is</u>
the length side of the square is
Part b) The volume of a cube shaped block is 64 cubic centimeters
we know that
the volume of a cube is equal to
where
b is the length side of the cube
in this problem we have
<u>Find the length side b</u>
therefore
<u>the answer Part b) is</u>
the length side of the cube is
