If a height of a cone is doubled then keeping the same radius how much time the volume will increase

1 answer:

7 0

Volume of cone = pi* r^2 *h/3

If you double the height ;
New volume = pi * r^2 * 2h/3

So, new volume will be twice as much.

A rectangular poster is 50 cm long and 25 cm wide. If 1 cm is approximately .4 inches What is the perimeter of the poster

gulaghasi [49]

It will be 600in or 150cm.
Reason is perimeter is just adding up the sides so if you wanna find it in inches then you multiply 4 by each side and if it’s just cm then just add them all up

Answer:

When the probe reaches the ocean floor, the horizontal distance of the probe from the team's ship on the ocean's surface will be approximately 1625 meters.

Step-by-step explanation:

tan=opposite/adjacent

tan67.4°=3900/x

2.40=3900/x

cross multiply

2.40x=3900

divide via by 2.40

2.40x/2.40=3900/2.40

x=1625

When the probe reaches the ocean floor, the horizontal distance of the probe from the team's ship on the ocean's surface will be approximately 1625 meters

marlee spins a spinner and rolls 1-6 # cube. the spinner has 5 equal parts # 1-5 . what is the probability she will spin an even

forsale [732]

The events are independant (i.e. what she rolls on the cube has no impact on how the spinner works). The probability of two independant events is given by:

$P_t = P_{cube} \times P_{spin}$

For the cube, 1/2 the numbers meet our requitment of being even, so:
$P_{cube} = \frac{Desired}{Total} = \frac{even}{total} = \frac{3}{6} =\frac{1}{2}$

For the spinner, there are 3 odds out of 5 (1, 3 & 5) so:
$P_{spin} =\frac{Desired}{Total} = \frac{odd}{total} = \frac{3}{5}$

and then:
$P_T = P_{cube} \times P_{spin}$
$P_T =\frac{1}{2} \times \frac{3}{5}$
$P_T =\frac{3}{10}$
