Answer:
The surface area of the cylinder is 326.56yd²
Step-by-step explanation:
To solve this problem we have to calculate the circle area and the lateral area
To calculate the area of the circle we use the following formula
a = area
r = radius = 4yd
π = 3.14
a = π * r²
we replace with the known values
a = π * (4yd)²
a = π * 16yd²
a = 50.24yd²
The area of the circle is 50.24yd²
To calculate the lateral area of the cylinder we use the following formula
a = area
h = heighti = 9yd
r = radius = 4yd
π = 3.14
a = 2 * π * r * h
we replace with the known values
a = 2 * 3.14 * 4yd * 9yd
a = 6.28 * 36yd²
a = 226.08yd²
The lateral area of the cylinder is 226.08yd²
Now we add the lateral area of the cylinder with 2 times the area of the circle and obtain the area of the cylinder
226.08yd² + (2 * 50.24yd² ) = 326.56yd²
The surface area of the cylinder is 326.56yd²
X^2-14+5 I’m not sure though
Y = mx + b; b = 6
<span>1 = 4m + 6; m = -5/4 </span>
<span>-5/4 = (1 + 2k) / (4 - k - 3) = (2k + 1) / (1 - k) </span>
<span>-5(1 - k) = 4(2k + 1) </span>
<span>5k - 5 = 8k + 4 </span>
<span>-3k = 9 </span>
<span>k = -3</span>
