Answer: a. 279.11meters
b. 2513.27 feet
Step-by-step explanation:
Circumference of a circle= 2πr
where r = radius of the circle.
In the picture, there are t
18 spokes, therefore the angle between any two spokes will be:
360° ÷ 18 = 20°
The arc length traversed by passenger will be= radius of the circle × the angle that is traversed by the passenger
radius = 200 feet.
He has traveled from M to J,that subtends 4 × 20 = 80°
= 80π/180 radian = 4π/9radian
The passenger has therefore traveled:
200 × 4π/9 = 800π/9
= (800×3.14)/9
= 279.11meters
Part B.
Full ride is equivalent to 2 × the circumference of the circle= 2 × 2πr
= 4πr
= 4 × 3.14 × 200
= 2512 feet
So,he would travel 4* 7 * 200 feet = 2513.27 feet
Answer:
a) 40 sides
b) 6840
c) 9 gegrees
Step-by-step explanation:
interior angle= (<u>n</u><u>-</u><u>2</u><u>)</u><u>1</u><u>8</u><u>0</u>
n
so total number of sides is 40
b) Sum of interior angles= (n-2)×180
(40-2)×180
38×180
6840
c) Exterior angle = 360 ÷ n
360÷40 =9 degree
Answer:
How much would it cost to buy 10 pounds of peanuts?
Answer: $35
What is the cost per pound?
Answer: $3.50
Step-by-step explanation:
So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.
Well if she got 4 pounds for $14, we should try dividing 14 by 4.
14 divided by 4 = 3.5 ($3.50)
So the cost per pound is $3.50
Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.
10 x 3.5 = 35
So if she bought 10 pounds, she would play $35
