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
Answer: 170
Step-by-step explanation:
Hemisphere volume formula
V = (2/3)πr3
(2/3)•(3.14)•(2.5)^3=32.7 (33)
Cylinder volume formula
V=πr^2h
(3.14)(2.5)^2(7)=137.4 (137)
137+33=170
