Answer:
10 cm³
Step-by-step explanation:
According to Archimedes, if we place an object in water, the rise of the water in mL will be the volume of the object in cm³.
Without the rock, the water measures 20 mL.
With the rock, the water measures 30 mL.
The change here is 
, so 10 cm³ is the volume of the rock.
Hope this helped!
Answer:
the answer is 12x\y hope it helps
In radians, pi = 180 degree, Hence for 2pi = 360
degree.
For cos 0 = cos 2pi = 1
And
Sin 0 = sin 2pi = 0
While cospi = -1 and sinpi = 0
So
<span>A) </span>cos2pi
+ sin2pi = 1 + 0 = 1
<span>B) </span>cos2pi
– 1 = 1 – 1 = 0
<span>C) </span>1
– 2sin2pi = 1 – 2(0) = 1
<span>D) </span>2
sinpi cospi = 2 * 0 * (-1) = 0
<span>Hence “A” and “C” are correct.</span>
