The "how many times larger" part can be figured out by forming a ratio between the two diameters above:
Note that dividing the powers of ten corresponds to subtracting the denominator power from the numerator power of 10.
Answer:
Possible answers (6,-8) and (4,-4)
Step-by-step explanation:
These two possible answers show the line has a slope of -2
Answer:
B. y
Step-by-step explanation:
Recall that Cosine = Adjacent over Hypotenuse
The adjacent side of angle "a" is y and the hypotenuse is x
Thus, Cos A = y / x
Answer: Raja needs 150.72 cubic centimeters for each horn.
Step-by-step explanation:
Since the horns that Raja is making are cone shaped, then we would determine the amount of clay she needs by applying the formula for
determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
h represents the height of the cone.
r represents the radius of the cone
π is a constant whose value is 3.14
From the information given,
Height = 16 centimeters
Diameter = 6 centimeters
Radius = diameter/2 = 6/2 = 3 centimeters
Therefore,
Volume = 1/3 × 3.14 × 3² × 16 = 150.72 cubic centimeters
