Caroline knows the height and the required volume of a cone-shaped vase she’s designing. Which formula can she use to determine

timama [110]

Answer:

Option B. $r=\sqrt{\frac{3V}{\pi h}}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

Solve for the radius r

That means-----> isolate the variable r

Multiply by 3 both sides

$3V=\pi r^{2} h$

Divide by $(\pi h)$ both sides

$r^{2}=\frac{3V}{\pi h}$

square root both sides

$r=\sqrt{\frac{3V}{\pi h}}$

The perimeter of a school gym is 522 feet. The gym measures 80 feet wide. Determine the length of the school. PLEASE EXPLAIN THE

lidiya [134]

Total perimeter is 522 ft. I will guess the gym is a big rectangle.

Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W

We know 80 ft wide. so now we plug and chug the equation we came up with

P=522 ft
P=2L+ 2(80)

522=2L+ 160

L= 181

hope that helps

A Pringles chip can has a diameter of about 2.8 inches and a height of about 11.8 inches (close to real measurement) what volume

NARA [144]

Answer:

72.66 in³

Step-by-step explanation:

The volume of a cylinder of radius r and height h is given by V = πr²h.

Here we have V = πr²h = π([2.8]/2 in)²(11.8 in) = π(1.96 in²)(11.8 in) = 23.1 π in³, or approximately 72.66 in³

Answer:

A. 4.2 times

Step-by-step explanation:

Chlorine level of the pool as adjusted by Paula = 6.3 parts per million

Ideal Chlorine level as suggested by the magazine = 1.5 parts per million.

Thus, the number of times the ideal level of Chlorine that the current level is = current level ÷ ideal level

= $\frac{6.3}{1.5} = 4.2$

The current Chlorine level is 4.2 times the ideal Chlorine level.
