ONLY SOLVE THE THIRD QUESTION

The diagram shows the surface of a garden pond, made from a rectangleand two semicircles. The rectangle measures 3 m by 1.2 m.

(a) Calculate the area of this surface.
4.73 m^2

(b) The pond is a prism and the water in the pond has a depth of 20 cm. Calculate the number of litres of water in the pond.
946 litres

(c) After a rainfall, the number of litres of water in the pond is 1007. Calculate the increase in the depth of water in the pond. Give your answer in centimetres.
?

I solved the first and the second questions. Please solve the third question.

the answer is d

hope this

you'll have to attache the image of the bar graph in order for us to answer : )

step-by-step explanation:

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
