Circumference = 2πr or πd

The formula for circumference is 2πr (2 times pi times the radius)
2r = d (The radius x 2 = the diameter), so the circumference also = πd (pi times the diameter)

Given: x ∥ y and w is a transversal Prove: ∠3 ≅ ∠6 Parallel lines x and y are cut by transversal w. On line x where it intersect
SOVA2 [1]

Answer:

The missing reason in the proof is transitive property

Step-by-step explanation:

<u>Statement </u>                                    <u>Reason </u>

1. x ∥ y w is a transversal              1. given

2. ∠2 ≅ ∠3                                    2. def. of vert. ∠s

3. ∠2 ≅ ∠6                                    3. def. of corr. ∠s

4. ∠3 ≅ ∠6                                    4.  ??????????

From the statements 2 and 3

The previous proved statement to make use of the transitive property reason or proof

∴ 4. ∠3 ≅ ∠6                                    4. transitive property

Note: the transitive property states that: If a = b and b = c, then a = c.

An aquarium is a cylinder with a diameter of 203 feet and a height of 25 feet. What is the volume of the aquarium
lilavasa [31]

Volume formula for a cylinder is pi*r^2*h

h=height=25 feet

r=radius=101.5

Radius is half of the diameter.

Plug those numbers in: pi*101.5^2*25= 809136.822886= 8.09*10^5 hopefully this helps! ^-^
