A rectangle of length 14 cm and breadth 7 cm is folded into a right circular cylinder. How many revolutions does the cylinder need to make to cover an area of 784 sq. Cm

n = 8

Step-by-step explanation:

Given that,

Length and breadth of a rectangle are 14 cm and 7 cm.

The area of rectangle is given by :

Let n be the number of revolutions the cylinder need to make to cover an area of 784 sq.cm.

So,

Hence, there are 8 revolutions.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

yes
