Here is your answer buddy

Answer 2

Answer:

• Curved surface area of hemisphere = 1413 cm²

Step-by-step explanation:

Given:

• Total surface of hemisphere = 675π cm²

To Find:

• Curved Surface area of hemisphere.

Now, we know that,

⇒ Total surface area of hemisphere = 3πr²

⇒ 675 π = 3πr²

⇒ 675 = 3r²

⇒ r² = 675/3

⇒ r² = 225

⇒ r = √225

⇒ r = 15 cm.

Now, we will find total surface area of hemisphere,

⇒ Curved surface area of hemisphere = 2πr²

⇒ Curved surface area of hemisphere = 2 × 3.14 × 15× 15

⇒ Curved surface area of hemisphere = 1413 cm²

Hence, Total surface area of hemisphere = 1413 cm²
