Answer:
10054.4m^3
Step-by-step explanation:
Given data
Height= 32m
Diameter= 20m
Radius= 10m
The expression for the volume of a cylinder is given as
V= πr^2h
Substitute
V= 3.142*10^2*32
V= 3.142*100*32m^3
Hence the volume is 10054.4m^3

<h3>Known that</h3>
y = -2x² - 8x + 3
════════════════════
<h3>Way to do + explanation</h3>
#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
