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

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
