Answer:
11/12
Step-by-step explanation:
The surface area of a cylinder can be determined with this formula
sa = surface area of 2 circles + surface area of side
sa = (2 × π × r²) + (2 × π × r × t)
Find the value of r (radius)
r = 1/2 diameter
r = 1/2 × 14.2
r = 7.1 cm
Plug the numbers into the formula
sa = (2 × π × r²) + (2 × π × r × t)
sa = (2 × π × 7.1²) + (2 × π × 7.1 × 12.8)
sa = 100.82π + 181.76π
sa = 282.58π
sa = 282.58 (3.14)
sa = 887.3
The surface area is 887.3 cm². The answer is third option.
Answer:
b/4 +b + b-8 =73
2b + b/4 = 81
9b/4 = 81
9b =81 * 4
b = 9* 4
b = 36
The sides of the triangles are 9 inch, 28 inch and 36 inch respectively
