Answer: 7.5²π square centimeters. OR 56.25π cm²
Step-by-step explanation:
Circumference = diameter × π
So the diameter is 15 cm
Area = πr²
Radius is half the diameter, so 15/2 or 7.5
Area = (15/2)²π cm²
Answer:
2.3cm x 4cm =
No, it is incorrect. The line should be solid, not dotted, because it's a ≤ sign, not a < sign.
11 - 3i = 44 (move 11 to the right side and add minus)
-3i = 44-11
-3i = 33 (dive it by -3)
i = -11
