The radius of a coin is measured to be 2.3 cm. Take π = 3.14. a-
The number of significant figures in the area of the coin is .

b-
The area of the coin to the correct number of significant figures is cm2.

16.6106

Step-by-step explanation:

area =3.14×2.3×2.3=16.6106cm

area=pie radius squared

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

thats not a system of equations, that is a solution
