Answer:
D) 144π sq. units
Step-by-step explanation:
The formula for finding the surface area of a sphere is 4π
Substitute 6 in for r. 4π = 144π
Answer:
Step-by-step explanation:
V=4/3πr^3
288πcm^3=4/3×π×r^3
288π×3cm^3=4πr^3
864π=4πr^3
r^3=216
r=6cm
Answer: 94.24 feet.
Step-by-step explanation:
1. To solve this exercise you must apply the formula for calculate the perimeter of a circle, which is shown below:
Where 
is the radius of the circle.
2. You can calculate the radius of the circle by dividing the diameter by 2, as following:
3. Substitute this value into the formula. Then, you obtain that the result is:
Answer:
Imagine the function y = absolute value(x). It looks like the English letter "V". The bottom of our V (i.e f(x) touches the x-axis when x = 6, so the "V" graph has been translated 6 units to the right of the origin. But when x = 6 the value of f(x) is 0-4 = -4 so the tip of the V is located 4 units below the x axis. Summary: g(x) looks like the absolute value function but is translated 6 units to the right of the origin and 4 units down
Step-by-step explanation:
Answer:
Angle BCA = 90
Step-by-step explanation:
A triangle inscribed inside of a circle using the diameter as it's hypotenuse is a right triangle
Where the angle opposite of the hypotenuse ( or diameter ) is the right angle
Angle BCA is the angle opposite of the diameter
Hence BCA = 90
