The problems below are all about ray method and mirror formula. Can you show to me how can I solve the following step by step and also can you make an illustration for each of the numbers?

Referring to #3 problem...What is the size of the image formed? * Referring to #4 problem..What is the size of the image formed? O 12 cm O 14 cm O 16 cm O 18 cm4. An object. which is 6 cm tail. is 25 cm from a concave mirror with a radius of curvature of 80 cm. What is the distance of the image from the mirror? *Note: Do image formation using Ray Method and use the mirror formula to solve for the unknown variables. * O 55.5? cm 0 -55.57 cm 0 75.44cm Q - :544 cm 2. How far must a girl stand in frent of a cancave mirrOr of radius 120 cm in order to see and erect image of her face four times its true size? * 3. A concave mirror has a radius of curvature of 4 m. A doll. 42 cm high. is placed 3 m in front of the mirror. What is the distance of the image frOm the mirror? *Note: Do image formation using Ray Method and use the mirror formula to solve for the unknown variables. *
