A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.
SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches
b.) The formula for the SA of a cone is:
SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches
Answer:
see below
Step-by-step explanation:
6(y(2)−4)
=(6)(y(2)+−4)
=(6)(y(2))+(6)(−4)
=12y−24
6(y2−4)
=(6)(y2+−4)
=(6)(y2)+(6)(−4)
=6y2−24
- -- There are 260.714 weeks total in 5 years.
But you can round by doing this:
52*5=260
This is because you have 52 weeks in a year and 55 years so you multiply.
r ÷ 12 or r/12
<h3>
Further explanation</h3>
Given the word phrase: the quotient of r and 12.
An algebraic expression for it is 
<u>Notes:</u>
The quotient is the ratio of two quantities to be divided or the number obtained by division. Synonyms for the quotient are proportion, ratio, or fractions.
An algebraic expression for the quotient of a and b is 
- 'a' is called a dividend
- 'b' is called a divider
- The quotient is the result derived after dividing the dividend by the divisor.
The quotient, a dividend, and a divisor represent the fundamental components of a division equation.
<u>Another example:</u>
A car requires 10 liters of fuel to travel 60 km. Determine the quotient of the distance of the car with fuel (in km/L).
The quotient (or ratio) is



Consider the same method as follows.



This means that the car can travel a distance of 6 km for every 1 L of fuel.
Kilometers per liter is a unit used to measure fuel economy and we see this as one example of the use of the quotient (or ratio).
