The formula for the volume of a cone is useful for this.
V = (1/3)π × r² × h
Substituting the given information, you have
V = (1/3)×3.14×(2 in)²×(18.3 in)
V ≈ 76.616 in³
Your best choice is ...
C. 76.62 cubic inches
Answer:
b
Step-by-step explanation:
at the left hand side the coefficient is 3
Answer:
27
Step-by-step explanation:
specific probability = number of specific possibilities divided by number of total possibilities.
the number of total possibilities is 72 (we can pull one out of 72).
the probability of pulling a red back is 3/8.
so, to find the actual number of specific possibilities (actual number of red balls in the overall sample size of 72) we need to bring this ratio of 3/8 to an expression of x/72.
what is the factor to turn 8 into 72 ? 9.
8×f = 72
f = 72/8 = 9
to keep the ratio unchanged in its dimension, we need to apply the same factor to 3 to get x.
3/8 × f/f = x/72
3/8 × 9/9 = x/72
3×9 / 72 = x/72
3×9 = x = 27
so, the probability ratio based on actual possibilities (number of balls available) is 27/72
=>
there are 27 red balls in the bag of total 72 balls.
Answer:
2,6
Step-by-step explanation:
2 2/3 means 2 + 2/3
2 2/3 = 8/3
8/3 = 2,6
So 2 2/3 = 2,6
