3a+b²=3(3)+5²=34
therefore 34 is the answer
The volume of cone is 24
or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Step-by-step explanation:
The given is,
Formula for volume of cone, 
Where, B = 
Volume, 
From the given,
Radius, r = 3 centimeters
Height, h = 8 centimeters
volume, 



Volume of cone, V= 24
(volume in terms of
)
( or )
Volume, V = (24 × 3.14 ) ( ∵
=3.14 )
V = 75.398 cubic inches
Result:
The volume of cone is 24
or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5
Step-by-step explanation:
What angles are you looking at?,
well one one angle is cos⁻¹∅=8/10 = cos⁻₁=0.8= 36.9
and the other angle is sin⁻¹∅=53.1
