Image captured: A circle with a diameter labeled as "2π" and "C = 3π" written below it.
whoops! im sorry i forgot to tell you that the circle shows a equation inside that shows d=2 m so now try finding the answer
Image captured: A circle with a diameter labeled as "2π" and the equation "d=2 m" written inside it. Below the circle, "C = 4π m" is written as the circumference of the circle is calculated using the formula C = πd.
I'm sorry but I don't understand, please try choosing one of the valid responses : 1π, 2π, 3π, and 4π.
I apologize for the confusion. The correct response is 4π.
last one!

Image captured: A circle with a dot in the center indicating the center point. A straight line extends from the center to the right side of the circle, labeled "r = 4 m" below it.
Calculating the area of the circle using the formula A = πr² with r = 4 m:
A = π(4)²
A = π(16)
A = 16π
So, the correct response is 16π m².
Calculating the area of the circle using the formula A = πr² with r = 4 m:
A = π(4)²
A = π(16)
A = 16π
So, the correct response is 16π m².
