Answer:

quick explanation abt the problem: Sa isang square na may measure na 10cm, may nakapaloob ng circle na 5cm and radius. Ano raw ang area ng natirang square

  • In order to get the area of the remaining square, you must get the area of each figure then subtract them
  • Para siyang getting the area of composite figure pero kukunin mo yung natira

Area of Square = s²

= (10cm)²

= 100cm²

Area of Circle = 3.14r²

  • use the symbol for pi.

= 3.11 (5cm)²

= 78.5 cm²

  • subtract them

100cm² - 78.5cm² = 21.5

So the total area of remaining square is 21.5cm²
