F(3), replace r with 3
f(3)=3.14(3)^2=3.14(9)=28.26
f(3)=28.26
Answer:
To the nearest centimeter
Radius= 5 cm
Step-by-step explanation:
Rate of filling balloon= 100cm³/s
Time to feel the balloon= 6 s
Volume of the filed balloon
= Rate*time
= 100*6
= 600 cm³
Volume of balloon= 4/3πr³
Volume of balloon=600cm³
600= 4/3πr³
(600*3)/4π= r³
1800/4π= r³
450/π= r³
143.239 = r³
5.232= r
To the nearest centimeter
Radius= 5 cm
So for this you need to set the two equations equal to each other. 20+.05x=10+.07x then solve. Subtract .05 from both sides and get 20=10+.02x. Then subtract 10 from the other side and get 10=.02x Isolate x by dividing 10 by .02. This leaves you with the answer of 500 texts.
Since there is no number for the number of pounds for the polar bear, you would use p to represent polar bears. The expression would be: 1578 - p. Good luck
