🤍 • Module 13 : Geometry Formulas Recap

Question 1

What is the formula for the area of a square?

Answer 1

A= a²

Question 2

What is the formula for the area of a rectangle?

Answer 2

A = length x width

Question 3

What is the formula for the area of a simple triangle?

Answer 3

A = 1/2 x base x height

Question 4

What is the formula for the area of a right-angled-triangle?

Answer 4

A = 1/2 x perpendicular sides

Perpendicular sides = adjacent side length + opposite side length

Question 5

What is the formula for the area of a trapezium?

Answer 5

A = 1/2 x (a+b) x height

Question 6

What is the formula for the area of a circle?

Answer 6

A = π x r²

Question 7

What is the formula for the area of a parallelogram?

Answer 7

A = base length x vertical height

Question 8

What is the formula for the volume of a pyramid?

Answer 8

V = 1/3 x Base area x height

Question 9

What is the formula for the volume of a sphere?

Answer 9

V = 4/3πr³

Question 10

What is the formula for the volume of a cylinder?

Answer 10

V = πr²h

Question 11

What is the formula for the volume of a cone?

Answer 11

V = 1/3πr²h

Question 12

What is the formula for the volume of a prism?

Answer 12

V = area of cross section x length

Question 13

What is the formula for the volume of a triangular prism?

Answer 13

Area of cross section = 1/2 x base x height
V = (1/2 x base x height) x length

Question 14

What is the formula for the surface area of a sphere?

Answer 14

SA = 4πr²

Question 15

What is the formula for the curved surface area of a cylinder?

Answer 15

CSA = 2πrh

Question 16

What is the formula for the total surface area of a cylinder?

Answer 16

TSA = 2πr² + 2πrh

Question 17

What is the formula for the curved surface area of a cone?

Answer 17

CSA = πr x slant height

Question 18

What is the formula for the total surface area of a cone?

Answer 18

TSA = πr² + πrl

(l = the slant height)
