7 0

Answer:

108 cm²

Step-by-step explanation:

The formula for the lateral area of a pyramid such as this is ...

LA = 1/2Ps

where P is the perimeter of the base (6·3 cm = 18 cm) and s is the slant height (12 cm). Putting the given values into the formula gives ...

A = 1/2·(18 cm)·(12 cm) = 108 cm²

___

The formula gives the total area of the 6 triangular faces. Each face has an area of ...

A = 1/2·b·h = (1/2)(3 cm)(12 cm) = 18 cm²

Then the total area of the six triangles is ...

6 · 18 cm² = 108 cm²

pantera1 [17]

Answer:

<h2>The answer is 615 m²</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

r = 14 m

π = 3.14

The area of the circle is

A = 3.14 × ( 14 ) ²

= 3.14 × 196

= 615.44

We have the final answer as

<h3>615 m² to the nearest whole number</h3>
