What is the area of the radius 7 cm?
Put the values of radius r and pi constant in the formula and solve it to get the answer. We have to find the area of the circle. $ \Rightarrow $The area of the circle=$\pi {r^2}$where r is radius of the circle and $\pi $ is pi constant. The area of the circle of radius $7$cm is $154{\text{ c}}{{\text{m}}^2}$.
How do you find the area of a circle with a radius of 7?

How do you find the area of a circle?
Area of a circle diameter. The diameter of a circle calculator uses the following equation: Area of a circle = π * (d/2) 2. Where: π is approximately equal to 3.14. It doesn’t matter whether you want to find the area of a circle using diameter or radius – you’ll need to use this constant in almost every case.
Which is the cut off part of a circle?
>A sector of a circle is section of a circle between two radii. You can think of it as a giant slice of pizza. >It’s a “cut-off” part of a circle, limited by a chord or a secant. >It’s an angle with the vertex in the center, whose arms extend to the circumference.
