A right square pyramid is pictured below. if l is 15 cm and x is 18 cm, what is the surface area of the pyramid?

Nady [450]

Answer:

The surface area of square pyramid is 953.64 cm² .

Step-by-step explanation:

Given as for a square pyramid :

The height of pyramid = l = 15 cm

The base of square pyramid = x = 18 cm

Now,

The surface area of square Pyramid = $b^{2} + 2b\times \sqrt{\frac{b^{2}}{4}+h^{2}}$

or , The surface area of square Pyramid = $x^{2} + 2x\times \sqrt{\frac{x^{2}}{4}+l^{2}}$

Or, The surface area of square Pyramid = $18^{2} + 36\times \sqrt{\frac{18^{2}}{4}+15^{2}}$

Or, The surface area of square Pyramid = 324 + 36 × $\sqrt{81 + 225}$

or, The surface area of square Pyramid = 324 + 36 × 17.49

Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²

Hence The surface area of square pyramid is 953.64 cm² . Answer

Which list is ordered from least to greatest?

olga55 [171]

It would be A. It is A because 5 is negative, 2.1 is negative, 0.3 and 3.1 are positive. Also 5 is greater than 2.1, so in this case -5 would be before -2.1.

What is the equation of a line passing through (-3, 7) and having a slope of -1 ?

il63 [147K]

Answer:

Using the information given, we can use the point-slope form:

y - y1 = m(x - x1)

y - 7 = -1(x + 3)

y - 7 = -x - 3

+7 +7

y = -x + 4, this is slope-intercept form

x + y = 4, this is standard form
