Chemical parison

The blown parison (with shape of a sphere) have a volume 1.5 liters. What is its surface?

Correct result:

S =  633.69 cm2

Solution:

V=43πr3 V=1.5 l=1.5 dm3 r=341.5π3=0.7101 dm=7.101 cm S=4πr2=4πr2=633.69 cm2 



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
