What is the area of a circle? What is the circumference of a circle? What is Photosynthesis? What is a Vector ?

Question

Accepted Answer

Area of a circle is the amount of space inside the circle. Circumference is the distance around the circle. Photosynthesis is the process by which plants convert light energy into chemical energy. A vector is a quantity that has both magnitude and direction.

The area of a circle can be calculated using the formula A = πr², where r is the radius of the circle.
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.
Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.
A vector can be represented graphically as an arrow, with the length of the arrow representing the magnitude of the vector and the direction of the arrow representing the direction of the vector.

Accepted Answer

Area of circle is A=πr2 and circumference is C=2πr.

Photosynthesis is process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

And vector is ameasurement or a quantity that has both size and direction.

Accepted Answer

The area of circle is 22/7(pi) r^2.... where r= radius of circle

Circumference of a circle is 2×3.14(pi)×r .... where r= radius of that circle

Photosynthesis is a process by which plant produce glucose , O2 by using sunlight , CO2, H2O

Vector represented graphically as an arrow, arrow representing magnitude of the Vector and direction of arrow represent direction of Vector
