Step-by-step explanation:
Option C
The ratio for the volumes of two similar cylinders is 8 : 27
<h3><u>
Solution:</u></h3>
Let there are two cylinder of heights "h" and "H"
Also radius to be "r" and "R"
Where π = 3.14 , r is the radius and h is the height
Now the ratio of their heights and radii is 2:3 .i.e
<em><u>Ratio for the volumes of two cylinders</u></em>
Cancelling the common terms, we get
Substituting we get,
Hence, the ratio of volume of two cylinders is 8 : 27
Answer: 5%
Step-by-step explanation:
A meteorologist predicted that Monday's hight temperature would be 76F and on Monday, the temperature reached 80F.
The percentage error will be
Percentage error=
(Exact value-Forecasted value)/exact value x 100
= 76-80/80 × 100
= -4/80 × 100
=4/80 × 100
= 400/80
= 5%
The percentage error is 5%.
