Answer: The area of the circle is 452.16 square units.

Step-by-step explanation:

To find the area of a circle you need to use the area of a circle formula. The formula is A= π x r^2.

π= 3.14

r= 12

The r is radius which is half of the diameter. When you apply the formula you get :

A = 3.14 x 12^2

A= 3.14 x 144

A= 452.16

Tell what whole number you can substitute for A in each list so the numbers are ordered from least to greatest. If there is none
hodyreva [135]

Answer: None

Step-by-step explanation:

If A=4, say for example, our list becomes: 3/4, 4/5, 75%.

This in decimal form becomes: 0.75, 0.8, 0.75 which is clearly not in ascending order.

If A =5, the list becomes 3/5, 5/5, 75% which clearly is 0.6, 1, 0.75 which is also not in ascending order.

For any value of A greater than 5, the second term A/5 is greater than 1 thus being less than the third term 0.75.

Therefore there is no whole number A that makes the list true.

Identify the lateral area and surface area of a regular triangular pyramid with base edge length 6 cm and slant height 13 cm.
Law Incorporation [45]

The lateral area is 117 square centimeters and the surface area is 292.72 square centimeters

<h3>How to determine the lateral area?</h3>

The given parameters are:

  • Base length (b) = 6
  • Slant height (l) = 13

The lateral area is calculated using:

Lateral = 0.5 * (Perimeter of base) * Slant height

This gives

Lateral = 0.5 * (3 * 6) * 13

Evaluate

Lateral = 117

Hence, the lateral area is 117 square centimeters

<h3>How to determine the surface area?</h3>

The surface area is calculated using:

Surface = l²√3

This gives

Surface = 13² * √3

Evaluate

Surface = 292.72

Hence, the surface area is 292.72 square centimeters
