Answer:
1,Area = πr² Circumference = 2 πr So first we solve for r from area: 25 π = πr² 25 = r² r = 5 So we know that radius is 5 cm. Now substitute r to 5 in circumference formula: C = 2π(5) = 10π
2.126 cm2
3. Tank a
Step-by-step explanation:
6 2/3
3*6=18
20-18=2
If -pi/3, the answer would be -1.05. If positive pi, then it's 1.05.
