A semicircular region circumscribes a circle which symmetrically fits

1.	A semicircular region circumscribes a circle which symmetrically fits into it. If a dice is rolled inside the semicircular part only what is the probability that the dice will fall in the circular region please don't give useless answer it is urgent
Answer» ONG>Answer: Radius of semi - CIRCULAR PIECE =14 cm Circumference of semi - circle = πr=722×14 =44 cm ∴ Circumference of base of CONE =44 cm ⇒2πR=44cm⇒R=2×2244×7=7cm Radius of semi - circular sheet = slant height of conical cup ⇒l=14cm Now, R2+h2=l2⇒72+h2=142⇒h=196−49=147=73cm ∴ CAPACITY of cup =31πR2h=31×722×7×7×73=622.3cm3

Answer» ONG>Answer:

Radius of semi - CIRCULAR PIECE =14 cm

Circumference of semi - circle = πr=722×14

=44 cm

∴ Circumference of base of CONE =44 cm

⇒2πR=44cm⇒R=2×2244×7=7cm

Radius of semi - circular sheet = slant height of conical cup ⇒l=14cm

Now, R2+h2=l2⇒72+h2=142⇒h=196−49=147=73cm

∴ CAPACITY of cup =31πR2h=31×722×7×7×73=622.3cm3
