Step-by-step explanation:
(1)
Calculate the circumference (C) of the wheel
C = πd (d is the diameter )
= 3.14 × 8 = 25.12 cm
Now divide the distance travelled by the circumference.
times rotated = 12560 ÷ 25.12 ≈ 500
----------------------------------------------------------------
(2)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Find r by using the circumference (C)
2πr = 50.24 ( divide both sides by 2π )
r = 50.24 ÷ 6.28 = 8 , then
A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )
-----------------------------------------------------------------
(3)
C = πd = 3.14 × 30 = 94.2 ≈ 94 m
2 divided by 4/10 is 5 its that easy.
Alyssa's average speed on the round trip is 540 Mies per hour.
We have given,
The speed of the jet Alyssa flew on from Boston to London was 480
mph.
On her return flight, the speed of the jet was 600 mph with a tail
wind.
<h3>What is the average speed?</h3>
a=inital speed
b=final speed
add 600 and 480 then divide by 2
That can be given by
Alyssa's average speed on the round trip is 540mph.

Answer:
13 full rows
Step-by-step explanation:
You would divide the 8 bags by 3/5 (the amount of soil it takes for a row) in order to get 13.3 continuing, but because the .3 isn't a whole row, you wouldn't count it.
