Volume of a Cylinder Formula:
- r is radius
- h is height
Step-by-step explanation:
<u>Step 1: Define</u>
Radius <em>r</em> = 2 in
Height <em>h</em> = 3 in
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cylinder Formula]: V = π(2 in)²(3 in)
- [Volume] Evaluate exponents: V = π(4 in²)(3 in)
- [Volume] Multiply: V = π(12 in³)
- [Volume] Multiply: V = 12π in³

This means our slope is equal to .
Hope this helped. :)
To find the area of the trapezoid, we only need the quantities a1 (long base), a2(short base) and h(height).
Area=(1/2)(a1+a2)*h
=(1/2)(9.9+4.7)(5.6)
=40.88 mm ²
Not sure what's expected to give for "type". Perhaps trapezoid or trapezium.
