<h3>What is Geometry?</h3>It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A birthday cake in the shape of the right-circular cylinder of radius 15 cm and thickness 10 cm is cut into smaller pieces.
One of the piece is shown.
Then the volume of piece of the cake will be
V = (30 / 360) x π x 15² × 10
V = 588.75 cm³

Answer:
Step-by-step explanation:
d = c/pi
so d = 62.8/pi
d = 62.8/pi or appr 19.99in
r = d/2
so r = 62.8/2pi or 31.4/pi appr 19.99/2
so
then
so
a = approximately 313.84
answer is rowan
Answer:
Step-by-step explanation:
we know that
The general equation of a quadratic function in factored form is equal to
where
a is a coefficient of the leading term
x_1 and x_2 are the roots
we have
substitute
Applying the distributive property convert to expanded form
therefore
