Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc =
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc =
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft
Answer:
the diagonal measurement from corner A to corner B=15 inches
Step-by-step explanation:
as we know that the loptop has the shape of a rectangle that means all it's angles are right angles. so we can use the pythogoras theorem to find out the diagonal of the rectangle.
let us denote the diagonal of rectangle by D and the sides of rectangle be denoted by X=12 and Y=9
so by using pythogoras theorem we have,
=225
D=15
Hence the diagonal measurement from corner A to corner B is 15 inches.
