The height and the slant height of a cone are 21 cm and 28 cm
respectively. Find the volume of the cone.

7546cm³

Step-by-step explanation:

From l² = r² + h² , we have

so, volume of the cone = ⅓ π r² h = ⅓ × 22/7 × 7√7 cm

So , volume of the cone = 1/3πr²h = 1/3×22/7×7√7×7√7×21 cm³

= 7546cm³

step-by-step explanation:

the shape,the size and the distance

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
