Answer:

A = 81π cm²

Step-by-step explanation:

The area (A) of the cross section is calculated as

A = πr² ( r is the radius )

Find r by using the given circumference.

Given the circumference is 18π and circumference (C) is

C = 2πr = 18π ( divide both sides by 2π )

r = 9, thus

A = π × 9² = 81π cm²

Can someone help me with these both

Hello,
so all you have to do is match the abbreviations to the triangles. The abbreviations stand for what is the SAME in both triangles, denoted by similar markings on equal sides and angles.

Abbreviations:
SSS = Side-Side-Side
SAS = Side-Angle-Side
ASA = Angle-Side-Angle
AAS = Angle-Angle-Side
HL = Hypotenuse-Leg

* Note - the angle side angle must go around the triangle in that order. ASA has the side BETWEEN the congruent angles.. SSA does NOT work.

(9.) ASA
(10.) AAS
(11.) SSS
(12.) No way to tell if congruent. (only 3 angles no side)
(13.) ASA
(14.) SAS
(15.) HL

Sophie [7]

Answer:

x = 11

y = 3

Step-by-step explanation:

-4y   -4y

+1   =2y-5

+5       +5

  6/2=2y/2

      3=y

2x-4=  18

  +4    +4

2x/2 = 22/2

      x=11
