Total surface area of cone: πrl + πr²
Assuming the bottom of the cone is closed.
r = r/2, l = 2l
Total surface Area = π*(r/2)*2l + π(r/2)² = πrl + πr²/4
Total Surface Area = πrl + πr²/4
Answer:
[0,+♾)
Step-by-step explanation:
|x| function is kinda like a half opened book from (0, 0) and |x+5| is from (–5, 0)
So we can't find any changes for y
so the domain is
[0, +♾)
Answer:triangles 20 12 28 and15 9 21
Step-by-step explanation:
Answer:
A = 9/100
B = -[1/100]
C = -[39/100]
Step-by-step explanation:
Given:
0.09x - 0.01y = 0.39
Find:
A,B,C
Computation:
Linear equation;
Ax + By + C = 0
So,
0.09x - 0.01y = 0.39
9x/100 - 1y/100 = 39/100
9x/100 - 1y/100 - 39/100= 0
So,
A = 9/100
B = -[1/100]
C = -[39/100]
Step-by-step explanation:
18(3x+1) = 54x+18
(6*9x) + (6*3) = 54x + 18
3(18x+2) = (6*9x)+(6*1)
(9*6x) - (9*2) = 18(3x-1)
54x+6 = (6*9x)+(6*1)
54x-18 = 18(3x-1)
