Area formula of a circle = πr2
π (8.5)2
Area= 226.98
Answer:
6
Step-by-step explanation:
To find the slope 'm' we use 2 points from the line, those are given in the statement:



Finally m=6
4a. 99m + 81 = 130m. 4b. 40 + 30z = 70z
5a. 24v + 18 = 41v. 5b. 12c + 16 = 28c
6c. 44 + 48v= 92v. 6b. 40 + 12s = 52s.
Answer:
34 degrees and 131 degrees
Step-by-step explanation:
Complementary angles always add up to 90 degrees
90 - 56 = 34 degrees (1)
180 - 49 = 131 degrees (2)
