Find the surface area of a square pyramid with base length of 16 cm and a slant height of 20 cm

Mathematics
1 answer:
Lerok [7]3 years ago
4 0

Answer:

The surface area of the square pyramid is 1,040 cm^{2}

Step-by-step explanation:

To find the surface area of the square pyramid, we make use of the mathematical formula.  

Mathematically, the formula for calculating the surface area A  of a square pyramid is :

SA = s^{2} + 2sl where s is the slant height and l is the base length

From the question, we can see that the slant height is 20cm and the base length is 16cm. We plug these into the equation above;

SA = 20^{2} + 2 * 16 * 20 = 400 + 640 = 1,040 cm^{2}

Whats the elasped time between 9:00 and 1:30
Tasya [4]

Answer:

4 hours and 30 minutes

Step-by-step explanation:

I'll assume you have a basic knowledge of time and know the sequence. So all you do is count to 1:00 and see how many steps you took. In this case 4, but then you have 30 minutes left. Add that to the 4 hours, and you have a total of 4 hours and 30 minutes of elapsed time.

Hope this helps :)

Solve x2 – 8x = 3 by completing the square. Which is the solution set of the equation?
vazorg [7]

Answer:

x = 4 ± \sqrt{19}

Step-by-step explanation:

Given

x² - 8x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 3 + 16

(x - 4)² = 19 ( take the square root of both sides )

x - 4 = ± \sqrt{19} ( add 4 to both sides )

x = 4 ± \sqrt{19}
