Answer:
62.8 m^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = (3.14) ( 2)^2 *5
V = 62.8 m^2
Answer:
V = 62.8 cm³

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>r</em> = 2 cm
<em>h</em> = 5 cm
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cylinder Formula]: V = (3.14)(2 cm)²(5 cm)
- Evaluate exponents: V = (3.14)(4 cm²)(5 cm)
- Multiply: V = (12.56 cm²)(5 cm)
- Multiply: V = 62.8 cm³

Answer: grid #1 and grid #3
Step-by-step explanation:
grid 3 is 100% out of 100% making one whole and grid 1 has 40 out of 100 squares filled. 100 + 40 = 140/140%
Hypotenuse = √[ (3)^2 + (-2)^2] = √13
sin(x) = -2/√13
csc(x) = 1 / sin(x) = - √13 / 2
cot (x) = 3 / (-2) = -3 / 2
