Answer:
The approximate length of segment EF is 7 unit
Step-by-step explanation:
Given figure is the graph having E and F coordinate
The coordinate of point E = ( 
, 
) = ( - 2 , -4 )
The coordinate of point F = ( 
, 
) = ( 2 , 2 )
Let The distance between the points E and F = D
So, D = 
or, D = 
Or, D = 
or, D = 
∴ D = 
I.e D = 7.21 unit
So, Approximate value of D = 7 unit
Hence The approximate length of segment EF is 7 unit . Answer
I’m pretty sure it’s B :))
Answer:
Surface Area is 56π cm²
Step-by-step explanation:
The area for a cylinder's surface area is
a=2πrh+2πr²
The cylinder base's radius is 4 cm
The cylinder's height is 3 cm
Putting into the equation:
a=2×π×4×3+2×π×4²
a=2π×4×3+2×π×4²
a=8π×3+2×π×4²
a=24π+2×π×4²
a=24π+2×π×16
a=24π+2π×16
a=24π+32π
a=56π
The surface area of the cylinder is 56π cm².
Answer:
y= 1.5x
Step-by-step explanation:
The y-intercept is 0 so we don't put anything there. The slope is 1.5. You can find the slope by using rise and run.
Answer.....15ft by 12ft
Explanation:
Area = Length × Width
180 = LW....make W the subject of formula
;W = 180/L
Perimeter = 2L + 2W
54 = 2L + 2(180/L)...sub W with the formula above...
then simplify the equation and obtain...
2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..
;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...
where W = 180/15 = 12ft
there you have...Length = 15ft and Width = 12ft
