1100

Part 1) arc AB=110°

Part 2) m∠BOC=36°

Part 3) arc ADC=214°

Step-by-step explanation:

we know that

Central angle is the angle that has its vertex in the center of the circumference and the sides are radii of it.

Part 1) Find the measure of arc AB

we know that

The measurement of the arc AB is that of the central angle AOB

m∠AOB=arc AB > by central angle

we have

m∠AOB=110°

therefore

arc AB=110°

Part 2) Find the measure of angle BOC

we know that

The measurement of the arc BC is that of the central angle BOC

m∠BOC=arc BC > by central angle

we have

arc BC=36°

therefore

m∠BOC=36°

Part 3) Find the measure of arc ADC

we know that

arc ADC+arc BC+arc AB=360° > by complete circle

we have

arc BC=36°

arc AB=110°

substitute

arc ADC+36°+110°=360°

arc ADC+146°=360°

arc ADC=360°-146°=214°

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
