To simplify it for you all get your area and divide it by pie, once you've done that, get that answer and square root it, then you should get your answer 🤓

for the last part, he divides 201.1 and π first, then takes the whole answer and square roots it,,. here is the whole schtick: take the original formula first: --> A=πr² substitute the given AREA, which is 201.1 square inches, so: --> 201.1 = πr² since we are finding RADIUS, we divide each side by π, so that only RADIUS will be left on one side: --> 201.1/π = πr²/π we cancel the two π's on the right side, so only RADIUS SQUARED (r²) is left on the right side: --> 201.1/π = r² (i will flip the equation) now, you have to get rid of the ² next to the r, so you SQUARE ROOT both sides of the equation: --> √r² = √201.1/π the ² next to the r is cancelled out, then divide what's inside the square root first: --> r = √[201.1/π] the WHOLE answer you have to square root: --> r = √64.0121181116 and here is the final answer, hope it was clear!: --> r = 8.00075734613 or 8.0 inches

there is supposed to be a √ symbol on your calculator you put the symbol behind the number that you are trying to square root [take the original formula first: --> A=πr² substitute the given AREA, which is 201.1 square inches, so: --> 201.1 = πr² since we are finding RADIUS, we divide each side by π, so that only RADIUS will be left on one side: --> 201.1/π = πr²/π we cancel the two π's on the right side, so only RADIUS SQUARED (r²) is left on the right side: --> 201.1/π = r² (i will flip the equation)] the square root part: now, you have to get rid of the ² next to the r, so you SQUARE ROOT both sides of the equation: --> √r² = √201.1/π the ² next to the r is cancelled out, then divide what's inside the square root first: --> r = √[201.1/π] the WHOLE answer you have to square root: --> r = √64.0121181116 and here is the final answer, hope it was clear!: --> r = 8.00075734613 or 8.0 inches
