117.8 in²
73.6in³
Explanation:
the pipe is in the shape of a open cylinder. the surface area = πdl
π = 3.14
l = length
d = diameter
volume of a cylinder = nr^2h
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
n = 22/7
r = radius = 2.5/2 = 1.25
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x (1.25^2) x 15 = 73.6
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
