Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is,
cm³
Height of the cylinder,
cm
Let the radius be 
Using the formula for volume of cylinder,

Plug in 3165.12 for
, 7 for
and solve for
.

Therefore, the radius of the cylinder is nearly 12 cm.
36 for the first one 39 for the second one
Answer:
5√13 = c OR 18. 0
Step-by-step explanation:
Using the Pyhtagorean Theorem, we will solve for x (in this case our hypothenuse)
a2 + b2 = c2
10(square) + 15(square)= c2 .....10*10 = 100 and 15* 15= 225
100 + 225 = c2
325= c2
√325 = c
5√13 = c OR 18. 0
Answer:
80°
Step-by-step explanation:
<u>The angles of a triangle must add up to 180°.</u>
40° + 60° + missing angle = 180°
100° + missing angle = 180°
<em>subtract 100° from both sides</em>
missing angle = 80°
Answer: B, D, E
Step-by-step explanation:
Statement 1 cannot be true because f(1)<0.
Statement 2 might be true.
Statement 3 cannot be true because if f is continuous, then for some value between -1 and 0, f(x) is positive by the Intermediate Value Theorem.
Statement 4 might be true.
Statement 5 might be true
