Answer:
18.84 square inches
Step-by-step explanation:
Distance across = diameter. The area formula for circles is A= πr. r in here means radius which is 6 inches (half of diameter). π is generally 3.14 or 22/7 depending on the question. multiply the value of π and 6, then you get the answer.
The answer is D because it asked 7 or more
Answer:
1 and 4 should be the answer since 1 is 4 just angled differently
^-^
The answer is (rounded to the nearest tenth) about 5.7 and since neither 18 or 2 have a perfect square, so this is irrational.
