A = a^2 = 121
so a = 11
answer
11 inches
Answer:
1⅙ gal
Step-by-step explanation:
⅔ × ⁷/₄ Cancel 2s
= ⅓ × ⁷/₂ Multiply numerators and denominators
= ⁷/₆ Convert to a mixed number
= 1⅙
The container holds 1⅙ gal when it is ⅔ full.
Answer:

Step-by-step explanation:
Given:
The radius of a cylindrical gift box = 
The height of the gift box is three times the radius.
Question asked:
What is the surface area of the cylinder ?
Solution:
The height of the gift box is three times the radius means,

Now, surface area of the cylinder = 
\\=8\pi x+2\pi(16x+4)\\=8\pi x+32\pi x+8\pi\\=40\pi x+8\pi\\=8\pi(5x+1) \ Taking \ common](https://tex.z-dn.net/?f=%3D2%5Cpi%5B4x%2B1%5D%284x%2B1%2B12x%2B3%29%5C%5C%3D8%5Cpi%20x%2B2%5Cpi%2816x%2B4%29%5C%5C%3D8%5Cpi%20x%2B32%5Cpi%20x%2B8%5Cpi%5C%5C%3D40%5Cpi%20x%2B8%5Cpi%5C%5C%3D8%5Cpi%285x%2B1%29%20%5C%20Taking%20%5C%20common)
Therefore, surface area of the cylinder is
.
