Answer:
<h2>351. 86 yd² </h2>
Step-by-step explanation:
As = 2πrh + 2πr²
where r = 4, h = 10
plugin values into the equation:
As = 2π (4) 10 + 2 π (4)²
As = 251.33 + 100.53
As = 351. 86 yd²

Answer:
n = 2
Step-by-step explanation:
1/2(n-4) - 3=3- (2n+3)
Expand the brackets.
1/2n-2-3=3-2n-3
Add or subtract the like terms.
1/2n-5=-2n
Add 2n and 5 on both sides.
1/2n+2n=5
Add like terms.
5/2n = 5
Multiply both sides by 2/5.
n = 5 × 2/5
n = 10/5
n = 2
