Answer» ANSWER: Step-by-step explanation: SURFACE AREA of sphere=1386 cm² 4πr² =1386 4×22/7×r²=1386 r²=1386×7/22×4 r²=441/4 r=21/2=10.5 cm Volume of sphere = 4/3πr³ =4/3×22/7×10.5×10.5×10.5 =237699 cm³

IF THE SURFACE AREA OF A SOLID SPHERE IS 1386 cm^2 THEN THE TOTAL SURFACE AREA OF THE SOLID HEMISPHERE OF THE SAME RADIUS IS

Answer»

ANSWER:

Step-by-step explanation:

SURFACE AREA of sphere=1386 cm²

4πr² =1386

4×22/7×r²=1386

r²=1386×7/22×4

r²=441/4

r=21/2=10.5 cm

Volume of sphere = 4/3πr³

=4/3×22/7×10.5×10.5×10.5

=237699 cm³
