A hose has a diameter of 8mm and a length of 10m. find the surface area and round to the nearest mm squared.

about 351.86 mm

Step-by-step explanation:

A = 2πRH+2πR^2

the diameter is given 8mm. since we need the radius, the radius is half the diameter, half of 8 is 4.

The length that given can be used as the height which would be 10.

R=4 & H=10

2π(4)(10)+2π(4)^2

Area is about 351.86 mm

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
