Answer:
x=3
Step-by-step explanation:
if the equation is 2x=6 then you'd do 6/2 and 2x/2 to cancel out the 2 and get x=3
Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.
Option A) is the correct answer.
<h3>What is the height of the oblique cylinder?</h3>
From Cavalieri's principle, the volume of an oblique cylinder is expressed as;
V = base area × h
V = πr² × h
Given that;
- Radius r = 9cm
- Volume of the oblique cylinder V = 486πcm³
- Height of the oblique cylinder h = ?
V = πr² × h
486πcm³ = π × ( 9cm )² × h
486πcm³ = π × 81cm² × h
486πcm³ = 81πcm² × h
h = 486πcm³ / 81πcm²
h = 6cm
Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.
Option A) is the correct answer.

Answer:
a(6)=2430
Step-by-step explanation:
a(1)=10
a(n)=3×a(n-1)
This is a geometric sequence, with ratio=3
a(2)=3×a(1)=3×10
a(3)=3×a(2)=3²×10
a(6)=3⁵×20=(27×9)×10=243×10=2430
