Question

find the surface area of a sphere of radius
1. 10.5 cm
2. 5.6 cm
3. 14 cm​

Answer 1

Answer:

answer 1=1323,2=448/25,3=5468

Answer 2

Answer:

surface area of sphere= 4 pi r²

4×22/7×(10.5cm)²=1,386cm²

surface area of sphere=4 pi r²

4×22/7×(5.6cm)²= 394.24cm²

surface area of sphere= 4 pi r²

4×22/7×(14cm)²= 2,464cm²
