Answer:
Step-by-step explanation:
Area = πr^2
r = diameter/2
r = 13/2
Area= 22/7 × (13/2)^2
= 22/7 × 169/4
Area = 132.79sqaure inch
Homeroom 6a is part to part
R + 3 = 2
First, subtract 3 from both sides. / Your problem should look like: r = 2 - 3
Second, simplify 2 - 3 to -1. / Your problem should look like: r = -1
Answer: r = -1
