Acone has a volume 1309 cm3 if the height of the cone is 8 centimeters find the radius

r = 12.5 (1 d.p.)

Step-by-step explanation:

The volume of a cone is given by:

We are given V and h. Sub these numbers into their respective variables,

Simplify,

r =

r = 12.5 (1 d.p.)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

$12. that is my answer.
