Patrica buys a round Dinner table. Units of measurements are removed

u cannot do a question without a measurement.

Step-by-step explanation:

see to find circumference it is 2×π×r(pie may be 22/7 or 3.14)

the area formula is π×r2

and semicircle formula is π×r+d

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

there is no grid
