A scientist is investigating the effects of salinity on fish development in the Atlantic Ocean. He places fertilized fish eggs i

n an aquarium that contains lower salinity than typical Atlantic Ocean water. He observes that the fertilized eggs fail to develop. He concludes that fish eggs do not develop in conditions with low salinity. Why is this an invalid conclusion? The experiment lacks an experimental group. The experiment does not measure any dependent variables. The experiment does not have a group tested in normal salinity. The experiment changes more than one variable at once. i need help ASAP PLEASE

Answer:

Area of given figure = 37.68 unit²

Step-by-step explanation:

Given:

Radius of given shape = 4 unit

Angle = 270°

Value of π = 3.14

Find:

Area of given figure

Computation:

Area of given figure = [Ф/360][πr²]

Area of given figure = [270/360][(3.14)(4)²]

Area of given figure = [0.75][(3.14)16]

Area of given figure = [0.75][50.24]

Area of given figure = 37.68 unit²

I don't know how to solve this. Anything will help!​
tigry1 [53]
Hello :) to solve this you would have to do invert sin (51/55) on your calculator. When you do that you will get 68.013 so I would round that and say that the angle is 68 degrees
