Answer:
r = 5
Step-by-step explanation:
The formula for volume of a cone is 
h = 6
V = 50π
r = 5
Answer:
3.95(3) + 8.95b = 47.65
11.85 + 8.95b = 47.65
Subtract 11.85 from both sides.
8.95b = 35.8
Divide 8.95 from both sides.
b = 4

Answer:
SAS requires two congruent sides and the included angle be also congruent
Given is the picture are congruent triangles
<u>ΔACB ≅ ΔECD, because:</u>
- AC ≅ EC, given
- BC ≅ DC, given
- ∠ACB ≅ ∠ECD, vertical angles
Area of a square is its side length squared...
A=s^2 solving for s...
s=√A
The perimeter of a square is 4 times its side length...
P=4s, and since s=√A
P=4√A, and we are told that A=100 in^2 so
P=4√100
P=4*10
P=40 in
which means either
or
. The equation has no solution, since
is always bounded between -1 and 1. The second has one solution at
, and any number of complete revolutions will also satisfy this equation, so in general the solution would be
where
is any integer.
So you could choose
and
.
