Answer:
The answer is 900 ×6= 5,400 u can use a calculator
Answer:
79 units²
Step-by-step explanation:
The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)

Answer:
the big number=36 the small number=20
Step-by-step explanation:
14x4=56
56+24=80
80/4=20
80-20=60
60-24=36
20+36=56
56/4=14
