Answer: The value of square root of 75 is 8.65.
Step-by-step explanation:
Since we have given that
a) Explain why her reasoning is incorrect.
Her reasoning is incorrect.
As we can write it as :
(b) Estimate the square root of 75 to the nearest thousandths without using your calculator. Show
As we know that
So, the square root of 75 would be :
Hence, the value of square root of 75 is 8.65.
since the number is going on the opposite it must be a negative integrer.
and since the number was 6 units away from 0, it should be the half point between the points.
number = 3
since it is going in the oppsoite direction it should be -3
Answer:
The answer is (5.91, 0.3).
Step-by-step explanation:
the lateral area of the cone is, well, the lateral area.
the total surface area of the cone is the lateral area plus the area of base circle.
so, the difference between both is the area of the base circle :
120pi - 70pi = 50pi
the area of a circle is
pi×radius²
and that is in our case
pi×radius² = 50pi
radius² = 50
radius = sqrt(50) = 7.071067812... ≈ 7.1 units
therefore, C is the right answer.
