If the measure of arc ac is 160°, what is the measure of angle abc?

a. 80°

b. 40°

c. 60°

d. 20°

∠ABC = 80°

A is correct.

Step-by-step explanation:

If the measure of arc AC is 160°.

Angle subtended on circle is half the angle subtended at center on same arc.

Please refer the attachment for figure.

Therefore,

where, arc AC = 160°

Hence, the measure of ∠ABC is 80°

the answer is 375 miles

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
