Formula for area of sector is as follows
A = πr² * (∅/360), Where r = radius and ∅ = angle of sector in degrees
Computing for the Area, we have
A = π(60²) * (60/360)
A = 600 π
Answer is 600π
Answer:
W = 14, L = 18
Step-by-step explanation:
If L = length and W = width, then:
252 = LW
L = W + 4
Substituting:
252 = (W + 4) W
252 = W² + 4W
0 = W² + 4W − 252
0 = (W + 18) (W − 14)
W = -18 or 14
Since W > 0, W = 14. Which means L = 18.
Answer:
You didn't provide the lines but I graphed it for you so you can match it up
Step-by-step explanation:
Write the given equation as
x = (1/2)y² or as y = √(2x)
Graph the given curve within the region (0,0) and (2,2) as shown in the figure below.
When the curve is rotated about the x-axis, an element of surface area is
dA = 2πy dx
The surface area of the resulting solid is
If the right end is considered, the extra area is π*(2²) = 4π
Answer:
The surface area of the rotated solid is (16π)/3.
If the right end is considered, it is an extra area of 4π.
