Volume of a cone formula: V = πr²*h/3

V = volume

r = radius

h = height

Solve with the given values.

V = π(7)²*19/3

V = π(49)*19/3

V = 153.86*19/3

V = 974.94...

Round to the nearest one.

974.94... → 975.0

Therefore, the answer is 975.0yd³

Best of Luck!

A ship goes at the rate of (3m-2) knots per hour. How far can it travel in (4m+9) hours?

Ber [7]

Answer: $12m^2+19m-18$

Step-by-step explanation:

Given

Speed of boat $v=3m-2\ \text{knots per hour}$

$\text{time t= }4m+9\ \text{hours}$

$\Rightarrow \text{Distance =speed}\times \text{time}$

$\Rightarrow \text{Distance d=}(3m-2)\cdot (4m+9)\\\Rightarrow d=12m^2+19m-18$

nydimaria [60]

Answer:

D.2.58

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.99}{2} = 0.005$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.005 = 0.995$ , so Z = 2.58.

The answer is given by option D.
