Answer:
Step-by-step explanation:
6 cm
480 I’m pretty sure ( a=LxWxH)
The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π
Answer:
(c) will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is
So the slope of the line which is perpendicular to y = 3x+2 will be
Now (a) Line is given as its slope is so it will be not perpendicular
(b) Line is given as its slope is so it will be not perpendicular
(c) Line is given as its slope is so it will be perpendicular to the line y = 3x+2
(d) Line is given as its slope is 3 so it will not perpendicular to the line y = 3x+2

===========================================================
Work Shown:
(whole length)*(external part) = (whole length)*(external part)
(EG)*(FG) = (SG)*(HG)
(2x+4)*(4) = (x+5)*(5)
8x+16 = 5x+25
8x-5x = 25-16
3x = 9
x = 9/3
x = 3
Use this x value to find EF
EF = 2x
EF = 2*3
EF = 6
