Answer:

difference between the areas = 75.31m²

aprroximately = 75m²

Explanation:

in order to calculate the difference between the areas of a circular target region with radius 5meters and 7meters will simply implies that we subtract the calculated area of radius A - calculated area of radius B

SOLUTION

recall,

area of a circle A = πr²

area of a circle A = 3.14 × (7)²

area of a circle A = 3.14 x 49

area of a circle A = 153.86m²

also,

area of a circle B = πR²

area of a circle B = 3.14 X (5)²

area of a circle B = 3.142 X 25

area of a circle B = 78.55m²

difference between the areas = (153.86 - 78.55)m²

difference between the areas = 75.31m² approximately 75m²
