Step-by-step explanation:
Answer:
Step-by-step explanation:
diameter = 12 cm
r = 12 ÷2 = 6cm
Volume of cylinder

πr²h = 825.192 cubic cm
3.14 * 6 * 6 * h = 825.192

h = 7.3 cm
Answer:
a = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° =
, then
cos60° =
=
=
( cross- multiply )
a = 4
Answer:
Temperature on Tuesday morning is
.
Step-by-step explanation:
Temperature is the measure in degrees how cold or hot a substance is. The three scale of measurements are: Celsius, Fahrenheit, and Kelvin.
In the given question, temperature on Monday morning is -14 degrees. Since it was given that the temperature on Tuesday morning is 4 degrees colder than that of Monday, then;
Temperature on Tuesday = -14 + (-4)
= -14 -4
= -18
Therefore, the temperature on Tuesday morning is
.
