Answer:
The radius of the cylinder is 3 inches.
Step-by-step explanation:
For any given cylinder, the volume can be expressed as:
volume = h
where r is the radius of its circular surface, and h is its height.
Given that: volume = 54π cubic inches, and the height = 6 inches.
then,
54 =
x
x 6
54 = 6
=
= 9
r =
r = 3
The radius of the cylinder is 3 inches.
Answer:
Step-by-step explanation:
Given a transversal that intersects a set of parallel lines, various angles are formed.
When given this situation in geometry, these angles have different names and statements (primarily theorems) which justify their relationship.
There are 8 primary types of possible angles of parallel lines including:
________________________________
According to what is given in the problem, we know that:
m∠3 = 135°.
________________________________
To solve for m∠7, we must identify the relationship that ∠3 and ∠7 have.
________________________________
Here is the solution in proof form:
_______________
Statement | Reason
m∠3 = 135° | Given
m∠3 ≅ m∠5 | Vertical Angles
m∠5 ≅ m∠7 | Corresponding Angles Theorem
m∠3 ≅ m∠7 | Transitive Property of Equality
m∠7 = 135° | Definition of Congruent Angles
