Answer:
1: a
2: a
3: a
4: b
Step-by-step explanation:
a right triangle means the pythagorean theorem applies
a^2 + b^2 = c^2
is true for the triange
a and b are the two shorter sides and c is the long side
test with values to see if true
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
true, it is a right triangle
3 root^2 + 8 root^2 = 11 root^2
3 + 8 = 11
11=11
true, it is a right triangle
3^2+ 10 root^2 = 19 root^2
9 + 10 = 19
19=19
true, it is a right triangle
3^2 + 5^2 = 6^2
9+25= 36
34= 36
false not a right triangle
i hope this helps
Answer:
makes no sense 8 is 11 ???
Step-by-step explanation:
Answer:
226.22 in^2
Step-by-step explanation:
Given data
Height l= 6in
Diameter= 12in
Radius= 12/2= 6in
The expression for the total surface area of a cone is given as
TSA= πrl+πr^2
substitute
TSA= 3.142*6*6+3.142*6^2
TSA= 113.112+113.112
TSA= 226.22 in^2
Hence the TSA is 226.22 in^2
