Given : गोले की त्रिज्या 10 सेमी

Radius of sphere = 10 cm  

To Find : गोले का कुल पृष्ठीय क्षेत्रफल

Total Surface area of of Sphere

1️⃣ 400π सेमी²

2️⃣ 300π सेमी²

3️⃣ 200π सेमी²

4️⃣ 100π सेमी²​

Step-by-step explanation:

गोले का कुल पृष्ठीय क्षेत्रफल  = 4πR²

R = त्रिज्या = 10 सेमी

Total Surface area of of Sphere = 4πR²

R = Radius = 10 cm

4π(10)²

= 400π

गोले का कुल पृष्ठीय क्षेत्रफल  = 400π सेमी²

Total Surface area of of Sphere = 400π  cm²
