Two solid splinical balls with
centers P & Q touch each other. The
ball lie inside and in contact with
"a hemispherical bond of centre
R. Given that p = 13 Q R = 16
can and PR = 19 cm. calculate
the radii of the bowl and
the two spherical balls.

Radii = 12 cm

Hope this helps!!

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
