Answer:
20 +4√2
Step-by-step explanation:
Find the total area the regular pyramid = A + 1/2ps
A is the Base area
p is the perimeter of the base
s is slant height
A = 1/2 * 4 * 4
A = 16/2
A = 8
p = 4 + 4 + (√4^2+4^2)
p = 8 + √32
p = 8 + 4√2
s = 4
Substitute
TSA = 8 + 8 + 4√2 + 4
TSA = 20 +4√2
Hence the total surface area is 20 +4√2
3 1/4 is the answer because your taking away 4 to 3 minus 3 is 3 1/4
This is true sometimes and false sometimes, depending on the numbers.
Answer:
A) h=0.5x+7
Step-by-step explanation:
given
initial height = 7 feet
growth rate = 6 in = 0.5 feet / year
let # of growing years = x
For a linear growth rate:
height after x years, h = initial height + (# of growing years) * (growth rate)
substiuting the values above into this equation
h = 7 feet + (x years) * (0.5 feet/year)
or
h = 7 + 0.5x (rearranging)
h = 0.5x + 7
