Answer:
The answer is C= 109.96 cm
Step-by-step explanation: Since it's a diameter, you'll have to split it in half to find the radius, from there, you can use the normal formula.
Answer:
Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, (
) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
Substitute,
Simplify,
Inverse operations,
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
Substitute,
I think the correct answer from the choices listed above is option D. For the function f(x) = (x − 2)2 + 4, the <span>vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.</span>
Answer:
9 meters
Step-by-step explanation:
Area of a parallelogram is base * height.
A = b * h
65.7 = b * 7.3
b = 9 meters
Answer:
= 18 red marbles
Step-by-step explanation:
Let x be the number of red marbles that must be added
Therefore;
New number or red marbles = x+12
Total marbles will be x+32
Thus;
The probability of selecting a red marble = (x+12)/(x+32)
Therefore;
(x+12)/(x+32)=3/5
5(x+12)=3(x+32)
5x+60+3x+96
2x=36
x=18
