The area of a triangular sail is given by the expression bh, where b is the length of the base and h is the height.
What is the area of a triangular sail in a model sailboat
when b = 16 inches and h = 9 inches?
in?
The area of a triangular sail in a sail model is

72in^2

Step-by-step explanation:

Area of triangle:

base*height/2

Area = 16*9/2

Area = 72in^2

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
