A bowling ball has a total diameter of 8.5 in. It consists of 2 parts. The inside is a spherical core with a diameter of 6 in.Surrounding the core is a layer of polyurethane.What is the volume of the polyurethane? Use 3.14 to approximate [tex] \/pi [tex] and round your answer to one decimal place.

___ in3

Answers

Answer 1

Answer: so first find the volume of the spere and the volume of the core then subtract the core from the squarere

so

volume of squrere formula 4/3pi times radius^3

diameter=2radius
diameter/2=radius

8.5/2=radius=4.25

4/3 times pi times 4.25^3=321.39

inner core= 4/3 times pi times r^3
diameter/2=6/2=radius=3

4/3 times pi times 3^3=113.04

subtract

sphere-core=321.39-113.04=208.352
round to 1 decimal place

208.4 in^3

the answer is 208.4 cubic inches

so the ratio is 18:12. you just divide each number down as much as you can so for this they are both divisible by 6 giving you a ratio of 3:2

A.
134 cm2

B.
170 cm2

C.
202 cm2

D.
238 cm2

Answers

Sorry! OK. I'll make this quick. Formula: A= A+B+C+D
A= 134 cm2
B= 170 cm2
C= 202cm2
D= 238 cm2
So, just add them altogether.
A= 744 cm (But I don't know what the exponent would be. Sorry!) I think that is how it would be. Its been a while since of done Area, though. Sorry about not knowing the exponent. And sorry if this isn't acurate.
