Given that ab is a diameter of circle o, find the missing angle and arc measures. itembank: move to bottom 116°154°26°32°64°

M arc CB=64°,M<AOC= 116° ,M arc AD=26°,M arc DFB=154°,M<CDB=32°.

Step-by-step explanation:

Measure of central angle is equal to the measure of intercepted arc .Given <COB= 64°.Hence M arc CB=64°.

<AOC= 180-64= 116°.( Angles made on a straight line is supplementary)

Measure of intercepted arc is twice the angle made on the circumference.

It is given <ABD= 13 °.Hence intercepted arc AD =2x13=26°.

Marc DFB=180-26=154°.Measure of arc of a semicircle is 180°.

M< CDB=64÷2=32°( angle made on circumference is half the angle made at the centre.)

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
