Step-by-step explanation:
Area of the square = a²
= 20²
= 400cm²
Area of the circle = πr²
= 22/7 × 9²
= 22/7 × 81
= 254.57cm²
Area of the shaded region = Area of the square - Area of the circle
= 400cm² - 254.57cm²
= 145.43cm²
Answer:
increase by 12
Answer: straight line across on the y axis on -2/3
Answer:32mm
area of triangle = 1/2 *base * height
192mm2 = 1/2 *b* 12mm
192 =6b
base=192/6
base= 32mm
