A section of guttering can hold up to 20 litres of rainwater. The diameter is 11cm. Work out the length in metres.

2.1 m

Step-by-step explanation:

The gutter is in the shape of a cylinder.

Its volume is 20 liters and its diameter is 11 cm (0.11 m).

Its radius is half of its diameter => r = 0.055 m.

The volume in cubic metres:

1 litre = 0.001 cubic metres

20 litres = 20 * 0.001 = 0.02 cubic metres

The volume of a section of guttering is given as:

where h = length of the guttering

Therefore:

The length of the section of guttering is 2.1 m long.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
