Find the area of a circle with a radius of 7.1 m to the nearest square unit.

Answers

Answer:

158 m2

Step-by-step explanation:

A=πr2=π·7.12≈158.36769m²

To find the area you do pi r squared. 7.1 squared is 52.54. 52.54 X pi =165.06. The answer is 165.06 cm2.

Is it possible to intersect a plane at more than one point with a line?

Answers

no it is not possible for a line to intersect a plane at more than one point because it is going through the figure once

Final answer:

In geometry, a line usually intersects a plane at one point, but if it runs parallel there are no points of intersection. If the line is part of the plane, there are infinite points of intersection.

Explanation:

In geometry, a line can intersect a plane in one point, no point, or the line could lie entirely on the plane. Usually, a line intersects a plane at a single point. However, if the line happens to run parallel to the plane, there would be no point of intersection as they are never going to cross each other. If the line lies on the plane, every point along that line intersects the plane, so technically there are infinite points of intersections.
