Answer:

7 feet

Step-by-step explanation:

Volume of a cyclinder = πr^2h

Volume of a cyclinder = 1952

π = 3.14

r = ?

h = 2r

Volume of a cyclinder = πr^2h

1952 = 3.14 * r^2 * 2r

1952 = 3.14 * 2r^3

1952 = 6.28r^3

Divide both sides by 6.28

r^3 = 1952 / 6.28

= 310.83

r^3 = 310.83

Find the cube root of both sides

r = 6.77 feet

Approximately 7 feet

A panda and a giraffe start moving towards each other when they are 300 feet apart. The panda is running at a speed of P feet pe

liq [111]

Answer:

(2P + G) feet/min

Step-by-step explanation:

Speed of the panda = P

Speed of the giraffe = P + G

Thus,

Speed of Panda + Speed of Giraffe = approaching time

= P + P + G

= 2P + G

Thus, The panda and the giraffe are approaching each other at a rate

of (2P + G) ft/min

Option C: $y = \frac{1}{2}x+\frac{5}{2}$ is the right answer

Step-by-step explanation:

Given points are:

(x1,y1) = (-1,2)

(x2,y2) = (3,4)

First of all, the slope has to be found

$m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{4-2}{3+1}\\= \frac{2}{4}\\=\frac{1}{2}$

The slope-intercept form of line is:

$y = mx+b$

Putting the value of m

$y = \frac{1}{2}x+b$

Putting (3,4) in equation

$4 = \frac{1}{2}(3) +b\\4 = \frac{3}{2} +b\\b = 4 - \frac{3}{2}\\= \frac{8-3}{2}\\=\frac{5}{2}$

Putting the value of b

$y = \frac{1}{2}x+\frac{5}{2}$

Hence,

Option C: $y = \frac{1}{2}x+\frac{5}{2}$ is the right answer
