Answer:
69. 14
or 22π
Step-by-step explanation:
Area of a circle = 2πr
and, radius, r = 11 cm
π = 22/7
Therefore the area of a circle with radius 11cm
= 2* π * 11 or 2 * 22/7 * 11
= 22π or = 484/7
= 69. 14
Volume of a sphere = (4/3) (pi) (radius)³
The sphere's volume is proportional to the cube of its radius,
so the radius is proportional to the cube-root of the volume.
The only way to double a sphere's volume is to increase
its radius by the factor of
∛2 = 1.26 (rounded).
Answer:
(using the numbers youve prpvided) 3444544
Step-by-step explanation:
214 x 8 x 2012 = 3444544
If you see this as <span>cos[2(3x)]
Then what we can do is </span>letting a = 3x to make it easier
Then it will be <span><span>cos2a
Hope this helps a lot</span></span>
