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

8 2/3 is the answer

step-by-step explanation: just use a calculator

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
