Given:
2 shapes: rectangle (tray) and circle (cake tin)
We need to find the area of each shape.
We need to convert mm to cm. 1mm = 0.1cm
600mm x 0.1cm/1mm = 60cm
500mm x 0.1cm/1mm = 50cm
Area of the Tray = 60cm * 50cm = 3,000cm²
Area of the cake tin = π r²
r = d/2 = 25/2 = 12.5cm
Area of the cake tin = 3.14 * (12.5cm)² 
Area of the cake tin = 3.14 * 156.25cm² 
Area of the cake tin = 490.625cm²
Area of the tray ÷ Area of the cake tin = number of cake tins that fit
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins.
Only 6 cake tins Jenny can fit on the oven tray at  one time.

C) In spring, when the water is high, the lake surges over the rocks.	
This sentence correctly uses the commas to go into more detail about spring.
Hope this helps!
 
        
                    
             
        
        
        
The phrase from the paragraph that makes a transition to a different idea is:
"In contrast".
<u>Explanation:</u>
Transition is word or phrase that connects two sentences or ideas that are expressed in an article or essay. 
It aids in expressing two ideas that may be different to each other, or may be in sync with each other. 
In the mentioned passage, the idea expressed about the changes in the mode of communication is aided by the transition phrase "in contrast", as it helps make the transit from the previous idea and concept to the new and updated one. 
 
        
             
        
        
        
Haven’t done this in a while but I think it’s complex 
complex contains an independent clause which includes subject and a verb in that sentence and cannot stand on its own. 
Independent clause can stand on its own and makes a complete thought
