What is the difference between the areas of a circular target region with radius 5m with radius 7m

difference between the areas = 75.31m²

aprroximately = 75m²

Step-by-step 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

answer: a and b

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
