Answer:
60π
Step-by-step explanation:
Hullo :D
I think this will be a piece of helpful info:
<em>The formula for finding the area of a circle if πd.</em>
<em />
In that case, we just substitute 60 (our d)
So the area will be 60π
If you want that multiplied, you'll get 188.4 (multiplying by 3.14)
Thus, the answer is
.
A=pir^2
c=2pir
a=pir^2=16
pir^2=16
divide both sides by pi or about 3.141592
r^2=5.0929581789406507446042804279205
sqrt both sides
r=2.2567583341910251477923178062431
circumference=2pir
circumference=2pi(2.2567583341910251477923178062431)
c=4.5135166683820502955846356124862pi
about 4.5pi square cm
Radius of cone is2.39cmor 2.4cm
volume of cone=45.19cm^3
Pi×r^2×h/3=45.19
22×r^2×7.5/7=45.19×3
r^2=45.19×3×7/22×7.5
r^2=948.99/165
r^2=5.7514545
r=2.39
Or we can say r=2.4cm
R u sure there Is no more to the question? I feel like there is a missing number somewhere :)
