Ok, so first convert both the numbers to improper fractions. (Multiply the denominator of the fraction by the whole number and add the numerator of the fraction)
Then keep the first number the same, change the division symbol to a multiplication symbol and use the reciprocal of the second number. (flip the numbers so that the denominator becomes the numerator and the numerator becomes the denominator.)
Then simply multiply across.
Answer:
324 pi . and 36 pi
Step-by-step explanation:
Area is pi r squared, so 18x18 is 324, times pi which is 324 pi
Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi

Answer:
Step-by-step explanation:
So we know that we have 1000 m in 1 km.
So convert 0.5 km to m we multiply 0.5 by 1000
0.5*1000 = 500
