SA= wh+lw+lp+ls
SA= 3(2)+7(3)+7(2.5)+7(2.5)
SA=6+21+17.5+17.5
SA=27+35
SA=62
Answer:
37.3032cm^2
Step-by-step explanation:
Given data
Diameter= 0.6cm
Radius= 0.3cm
Lenght = 19.5cm
Surface area (A) =2πrh+2πr^2
Substitute
A=2*3.14*0.3*19.5+2*3.14*0.3^2
A=36.738+0.5652
A=37.3032
Hence the surface area is
37.3032cm^2
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope. a parallel line must have the same slope.
in our case here it is -3.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
-4 = -3×-9 + b = 36 + b
b = -40
so, the full equation of the parallel line is
y = -3x - 40
Answer:
11.4
Step-by-step explanation:
b/sinB = a/sinA
b/sin(42) = 17/sin(88)
b = 11.38215401
{1,3, 4,5, 3,4 and 5,6} but I’m not sure.
