Answer: See explanation

Step-by-step explanation:

Circumference of a circle: 2πr

π = 22/7

r = d/2

r = 42/2

r = 21

2 × 21 × 22/7

42 × 22/7 = 924 ÷ 7 = 132

Circumference = 132m

Area of the circle: πr²

π = 22/7

r = 21

22/7 × (21²)

22/7 × 441 = 9702 ÷ 7 = 1386

Area = 1386 m²

Hope this helps!

I'm lost, please help (NO LINKS)​

Answer:

Adam's total cost: $9.20

Cindy's total cost: $9.20

Step-by-step explanation:

Since Adam and Cyndi's total bill costs $16, evenly splitting the cost means that each of them has to pay $8, not including the tip.

To find out the dollar value of their 15% tip, multiply $8 by 0.15:

$8 × 0.15 = $1.20.

Adam and Cindy will have to pay $8 (lunch cost) + $1.20 (tip) = $9.20 separately.
