Brian is measuring one of his family’s round dinner plates so that he can buy more plates of the same size. he found that it is 14 centimeters from the edge of the plate to the center of the plate. which is closest to the circumference, in centimeters, of the plate?

c = 2 pi r

radius is 14

2 * 3.14 * r

answer is 87.92 rounded up would be 88

Step-by-step explanation:

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

the correct answer is 5 6 and 7
