Answer: 14cm
Step-by-step explanation:
The diameter of a circle is twice the radius.
Therefore, the diameter = 2*7 cm = 14cm
1) 475
2)375
You need to multiply 25 by 27 and you get 675 then to get answer one you need to multiply 10 by 20 to get 200 the take 200 away from 675 to get 475 then do the same thing with the second problem 20x15 which is 300 the take 300 away from 675.
