Question

the area of the biggest possible Circle to be cut out from a square sheet of side 14 cm​

Answer 1

Answer:

49π

Step-by-step explanation:

area of the circle with diameter as 14cm

for proof that it is the biggest circle

you have to use differentiation

let the diameter of the circle be 14-x

x will be remaining length of the paper after the circle is cut

area= π((14-x)^2)/4 -----(1)

differentiate eq (1) w.r.t x --------(2)

now

equate eq(2) to 0 and find the x value

differentiate eq(2) w.r.t x and substitute the x value

if value less than 0 then the area will be max

if value more than 0 the area will be min

Answer 2

You should do it by yourself don't search for the answer
