Circumference of the smaller circle, using
, is approximately equal to 18.85 (I used the high floating point precision approximation of pi my calculator has in memory, then rounded to 2 decimal points.)
Using the formula
, which in English says "the smaller circle's circumference is equal to 20% of the larger circle's", we can substitute the known value S:
and solve for L:
.
So the larger circle has a circumference approximately equal to 92.5 units.
4/12= 2/6=1/3 So the answer is 1/3
Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Answer:
no
Step-by-step explanation:
the x value (-1) repeats therefore it ain't a function
Given:
- The right rectangular prism is made up of 48 cubes.
- Each cube has an edge length of 1/4 inch.
To Find:
- What is the volume of this prism?
Solution:
<u>Using formula: </u>
Substituting values in the formula:
Now,
Volume of 48 such cubes = Volume of 1 cube × 48 cubes
Hence,
- Volume of prism is <u>3/4 inch^3</u>
