Find the surface area of a square pyramid with base length of 16 cm and a slant height of 20 cm
1 answer:
Answer:
The surface area of the square pyramid is 1,040
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 = 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 = = 400 + 640 = 1,040

Answer:
d. x = -3
Step-by-step explanation:
<u />÷ (x+8)(x-2) = 0
f(x) / g(x) = 0
Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).
<u /> = 0 ------ square both sides
x + 3 = 0
solve for x:
x = -3
