Answer:
82% decrease
Step-by-step explanation:
<h2><u>Percentage </u></h2><h3><u>percentage change formula :</u></h3>the change = 5000-900 = 4100
the original = 5000
=
= 82 %
<h3><u>NOTE</u>:</h3>to find out if its an increase or decrease notice that the question says 5000 to 900. meaning
from 5000 you are reducing to 900 === hence decrease
<h3><u>the percentage change is : a percentage decrease of 82%</u></h3>Step-by-step explanation:
remember. the radius is always half the diameter.
volume of a cylinder
pi × r² × height
pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³
volume of a sphere
4/3 × pi × r³
and that volume should be the same as the cylinder. so,
4/3 × pi × r³ = pi×56.25×48
4/3 × r³ = 56.25 × 48
1/3 × r³ = 56.25 × 12
r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025
which would be 12.65148998... in.
Answer:
Solution given:
p=10mi
b=6mi
h=x.
by using Pythagoras law
h²=p²+b²
x²=10²+6²
x=
We can rule out the negative length.
Answer: b=4, h=18
