Find the lateral area of the cone in terms of pi. Radius 3cm, height 4

Mathematics
1 answer:
Alona [7]3 years ago

Lateral area of the cone = 15 π sq. cm

<u>Step-by-step explanation:</u>

Lateral area of the cone A = πr √(h²+ r²)

Here h = 4 cm and r = 3 cm

Plugin the values we will get the lateral area as,

A = π × 3 ×√(4² +3²)

  =  π × 3 ×√(16 +9)

 = π × 3 ×√(25)

 =  π × 3 × 5

  = 15 π sq. cm

How do i find the area for number 4?
ankoles [38]
<h3>Answer:  41 cm^2</h3>

Explanation:

Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles

  • The bottom rectangle has area of 4*8 = 32 cm^2
  • The top rectangle has area of 3*3 = 9 cm^2

The total area is therefore 32+9 = 41 cm^2

You can say "square cm" or "sq cm" in place of the "cm^2".

Tanzania [10]

Answer:

The slope is 2.

Step-by-step explanation:

The formula for slope is m = (y2-y1)/(x2-x1)

If we choose the points (0,2) and (1,4) we can plug these into our slope equation.

(4 - 2) / (1 - 0) = 2/1 = 2
