Answer:
14 cm
Step-by-step explanation:
Given:
A mug can hold 13.46 oz of coffee.
The radius of the mug is 3 cm.
Given that 1 equals 0.034 oz.
Question asked:
What is the height of the mug to the nearest centimeter ?
Solution:
Given that 1 equals 0.034 oz.
By unitary method:
0.034 oz = 1
1 oz =
13.46 oz =
A mug can hold 13.46 oz of coffee means volume of cylinder is given which is 395.88 . Now we can find the height of the mug by using volume of cylinder formula:
volume of cylinder =
By cross multiplication:
By dividing both side by 198
Therefore, height of the mug to the nearest centimeter is 14 cm.
Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
