Answer:
108
Step-by-step explanation:
Okay here we see a diameter of 6 which is a line that shows the width of the whole circle. The radius is half of the diameter. So its 3. So its asking to use 3 for pie and the formula is 4/3 pie r^3. So we do 4/3 times 3 times 3^3 and we get 108. I hope this helps.
Answer: x = 3
Step-by-step explanation:
Note that this triangle has 3 congruent angles. Therefore, it is an equilateral triangle. So, the sides will also be congruent.
So it can be said that : 6x - 3 = 3x + 6
+3
6x = 3x +9
-3x
3x = 9
/3
x = 3
By replacing x with 3, we can prove that these expressions all equal 15.
6(3) -3 = 18 - 3 = 15 . 3(3) + 6 = 9 + 6 = 15 . 5(3) = 15
B:Add
Because when multiplying two numbers written in scientific notation you will have to add the exponents of 10
