Answer:

about 50.8 cubic meters

Step-by-step explanation:

The formula for the volume of a cone is ...

V = (1/3)πr²h

Put the given values into the formula and do the arithmetic.

V = (1/3)π(3.4 m)²(4.2 m) = 16.194π m³

For π to calculator precision, this is ...

V ≈ 50.84 m³

For π = 3.14, this is ...

V ≈ 50.82 m³

Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters. What is the diagonal d

jolli1 [7]

Answer:

70.7 meters.

Step-by-step explanation:

We have been given that Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters.

Since we know that diagonal of a square is product of side length of square and $\sqrt{2}$ . So we will find diagonal of our given square plaza by multiplying 50 by $\sqrt{2}$ .

$\text{Diagonal distance across the plaza}=50\times \sqrt{2}$

$\text{Diagonal distance across the plaza}=50\times 1.414213562373095$

$\text{Diagonal distance across the plaza}=70.71067811865475\approx 70.7$

Therefore, diagonal distance across the plaza is 70.7 meters.

12x+7< -11 AND 5x−8≥40 need help asap

artcher [175]

Answer:

Step-by-step explanation:

Let's solve 12x + 7 < -11.

12x < -18

x < -3/2

Solving 5x − 8 ≥ 40 we get:

5x ≥ 48

x ≥ 48 / 5

Since it says AND, the answer is no solution.
