To find the circumference, multiply the radius by 2, then multiply by PI.
4 3/4 x 2 = 9 1/2
9 1/2 x PI = 9 1/2 x 3.14 = 29.83
Rounded to the nearest inch = 30 inches.
Grams as it's not rounded to the nearest thousand
Answer:
cos theta = adja/ hypo
adja=8
hypo=17
cos theta= 8/17=0.47
theta= cos^-1 0.47
theta=1.0815
to fine missing side, use Pythagoras
hypo²= oppo² + adja²
17²= oppo² + 8²
289-64=oppo²
oppo²=225
oppo=15
Let's look at the formula for the volume of a sphere:
Volume = (4/3) (pi) (radius)³ .
If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by (anything)³ .
Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by ∛(something).
In this question, the ratio of the volumes is 3 .
So the ratio of the radii (radiuses) is ∛3 = about 1.442 (rounded)
