A = π r^2
A = 9^2 <span>π
</span>A = 81<span>π
if using </span>π = 3.14 then
A = 3.14 x 81 = 254.47 ft^2
answer: 81π ft^2 or 254.47 ft^2
hope that helps
I’m not gonna lie I don’t know the answer I’m just answering random questions to get points I’m so sorry
Answer:
Here you go mate!
Step-by-step explanation:
Answer:
5430.85 square feet
Step-by-step explanation:
Height of the cylindrical part of the cilo = 25 feet
radius of the base cylindrical part of cilo = 8 feet
Now volume of cylindrical part of cilo =
Volume of cylindrical part of cilo =
= 
Now,
Height of the conical part of cilo = 6 feet
Radius of the conical part of cilo = 8 feet
Volume of the conical part of cilo =
=
Volume of the entire cilo =
since 
volume of entire cilo =
= 5430.85
9:6 I think. Because if you subtract 6 from 15 you get 9 and that is how many she needs to finish and she has already finished 6
