Answer:
x=12/5
Step-by-step explanation:
4x + 16 - x= 22 + 6
5x+16=28
5x=28-16
5x=12
x=12/5
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
It usually helps a person to get a better idea of how much or how big something is. I'm actually not sure why, but let's use an example. You got 38 out of 43 questions on a test. when you see 38/43 you don't really know how good that score is, but if you make it a percentage (Dividing the first number by the second to get the percentage) it's 88%. You know you did well on that test.
