The last option I'm thinking, hope this helps
Let's pick some simple points with which to set up an example for ourselves for this. Let's let the smaller radius be 1, and the larger, twice that, be 2. The radius itself is a single unit measure; in other words, it's measured as inches, feet, cm, etc., while the volume is a cubed measure. Volume is measured in inches cubed, feet cubed, cm cubed, etc. Therefore, if we have the radii measuring 1:2, we simply cube those single unit measures to find the ratio of their volumes. 1 cubed is 1, and 2 cubed is 8. So your answer for this is 1/8.
Answer:
1. 29.67°
2. 68.96°
3. 89.85°
Step-by-step explanation:
1. Reference angle = x
Opposite = 45 cm
Adjacent = 79 cm
Therefore:
(nearest hundredth)
2. Reference angle = B
Opposite = 14
Hypotenuse = 15
Therefore:
(nearest hundredth)
3. Reference angle = x
Adjacent = 238,900 mi
Hypotenuse = 92,955,807 mi
Therefore:
(nearest hundredth)
Hi,
first you should divide 130 (speed) by 2 (time), then divide 390 by 65 (result of 130 / 2)
Are = radius squared times pie so 12*12 = 144 so 144 times pi 3.14*144 = 452.16 is your answer
