Work out the size of an exterior angle of a regular pentagon

72°

Step-by-step explanation:

The sum of the exterior angles of a regular polygon = 360°

A pentagon has 5 exterior angles, thus

exterior angle = = 72°

Step-by-step explanation:

Regular pentagon has 5 equal sides.

Sum of exterior angles of any polygon = 360

Exterior angle of regular pentagon = 360/no. of sides

=360/5

=72

i understand 100% 10/10 hit or miss?

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
