No, a circle is a two-dimensional shape, whereas the Earth has three-dimensions.
Many people assume Earth is a sphere, however the Earth is wider at the equator than it is tall at the poles. This shape is described as an oblate spheroid.
The shape of the Earth is actually a rather complex figure called a geoid, which just means "Earth-shaped". It's roughly an ellipsoid (which is itself pretty close to a sphere), but one where the Southern Hemisphere bulges just a tiny more than the northern one, making it very slightly pear-shaped (with additional bulges in various places).
If by revolution you mean the spin on it's own axis this is more or less a perfect circle. If you are referring to it's orbit around the sun, this is elliptical, not a perfect circle.
The Earth rotates in not a perfect circle around the sun but in a oval shape.

Earth's shape is oblate spheroid.

Earth's eccentricity Eccentricity is defined as the difference in shape between an ellipse and a perfect circle. In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year.
Of coarse..... a circle
It is a nearly perfect circle.
About the same shape as an egg, or oblong. Not a perfect circle.
Oval or elliptical shaped. (Not a perfect circle)
The Earth rotates in not a perfect circle around the sun but in a oval shape.
The Earth rotates in not a perfect circle around the sun but in a oval shape.
All orbits are ellipses. Earth's orbit is elliptical, with a fairly low degree of eccentricity. This means that while it isn't a perfect circle, it isn't very far off.
The world is a "oblate spheroid" because it is not a perfect circle. The Earth bulges out around the equator.
You can take a round cup or glass and set it in the middle of the paper and then taking a pencil you can trace the outer edge of the cup. You should have a perfect round circle upon completion.
the moon isn't a perfect sphere its kinda like a oval in a way The shape of the moon is an oblate spheroid, just like earth
