26
Step-by-step explanation:
○= 7
□=5
◇=4 (The triangle)

Step-by-step explanation:
Firstly we calculate length of CB
/CA/^2 = /BA/^2 + /CB/^2
12^2 = 6^2 + /CB/^2
144 = 36 + /CB/^2
/CB/^2 = 144 - 36
/CB/^2 = 108
/CB/ = √108
/CB/ = 10.4cm
Sin55 = (/CB/)/(/CD/)
Sin55 = 10.4/(/CD/)
/CD/ = 10.4/sin55
/CD/ = 12.7cm
Answer:
188.495
Step-by-step explanation:
Given that,
h=7
r=3
Surface area of a cylinder = 2πr(h + r)
=2π×3(7+3)
=18.8495559215 (10)
=188.495
Answer:
62.83 cm is the length of the ribbon needed
The value of the exterior angle is the sum of the angles opposite. This is an equilateral triangle, so all angles are equal to 60 degrees.
60 + 60 = 120
So angle DAB is 120 degrees.
