Answer:
9.60πcm²
Step-by-step explanation:
Area of circular disk, A = πr²
Differntiate A with respect to r
dA/dr = π * (2r^(2-1)) /(2-1) + C
dA/dr = π * 2r/1
dA/dr = 2πr
dA = 2πr * dr
dA = 2πrdr
dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm
dA = 2π * 24 * 0.2
dA = 9.60πcm²
By taking a common denominator, we can find out that the simplified expression of the given expression is .
The given expression is -
---- (1)
We have to simplify the expression.
From equation (1), we have the given expression as -
Establishing common denominator , we have
Combining the numerator and common denominator, we have
Thus, the simplified expression of the given expression is which is obtained by taking a common denominator.
