pi is the pi times diameter
Step-by-step explanation:
multiply by 6.28 that's pi times r...hope it helps
Answer:
2 half cubes
Step-by-step explanation:
this has only half the width, you just need 1 more to make a whole, therefore 2
48
48 is the best answer to this. It is not 4. It is not 16 and it is not 24.
Answer:
2526.618
Step-by-step explanation:
To find the are of a circle you do r π²
So, 16 x π = 50.265, then 50.265² is 2526.618
Answer:
48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24
Step-by-step explanation:
Since The angles of a triangle add up to 90, then 8 + 3 + 4 should equal to 90 if multiplied by x.
Example:
x(8 + 3 + 4) = 90
x(15) = 90
15/15x = 90/15
x = 6
If x is equal to 6, then 6 times 8, 6 times 3, and 6 times 4, should equal their respective angles and add up to 90.
Example:
8 * 6 = 48
3 * 6 = 18
4 * 6 = 24
48 + 24 + 18 = 90
This means the angles are
48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24
