Possibly another mistake at 3a, Only 2 points (but i could be wrong)

Answer:
The volume of water in the vase is 
Step-by-step explanation:
A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:
r = 3 / 2 = 1.5 inches
To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.
The volume of a cylinder is given as:

The volume of the vase will be:

Hence, the volume of the water in the vase when it is 9/10 filled is:

Approximating to the nearest cubic inch, the volume of water in the vase is 
Answer:
area is length * width
12* 10 = 120cm
the answer is 120cm
Step-by-step explanation:
Jade hiked 1 1/4 miles on the trail. Gretta hiked 1 1/2 times as far on the trail as Jade.
Jade hiked = 
Gretta hiked =
[/tex] times Jade hiked
So Gretta hiked =
To multiply two fractions, we multiply numerator with numerator and denominator with denominator
Gretta hiked =
miles
