Answer:
99.33ft^2
Step-by-step explanation:
The surface area of a square pyramid is expressed as;
TSA = a²+2a√a²/4 + h²
Given that
a = 5ft
h = 7ft
Substitute
TSA = 5²+2(5)√5²/4 + 7²
TSA = 25+10√25/4 + 49
TSA = 25 + 10√(221/4)
TSA = 25 + 10(√55.25)
TSA = 25 + 10(7.433)
TSA = 25 + 74.33
TSA = 99.33ft^2
Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2
As it is a square all sides are equal so all sides are 12 feet long.
how many posts on one side?
First we find out how many lengths of 3 we have for 1 side:
12 / 3 = 4
And then multiply this by the amount of sides
4 * 4 = 16
We need 16 posts
1 - 1 - 1 - 1 - 1
1 1
1 1
1 1
1 - 1 - 1 - 1 - 1
Answer:
The one with the higher amount they put away
Step-by-step explanation:
Answer:
the graph is misleading because it uses 3-dimensional bars
I think its 3/10=0.3
2×(-0.15)= -0.3
and -0.3+0.3=so variable value is -0.15
