Answer 2

Step-by-step explanation:

pie marked as we know,

d=2r

area=2rh

now,2r/2rh=2/7

7(2r)=2(2rh)

14r=4×22/7×rh

14r=88rh/7

14=88h/7(r divides r)

H=88/7×14

H=88×2

H=176cm

now,area=2rh

(we found value of h)

=2×22/7×r×176

=44/7×r×176

Now,find area,through are find radius and diamete=2r
