Circumference of a cirlce=2πr
Data:
r=7 in
Circumference=2(3.141592....)(7 in)=43.9822...in≈44 in.
Answer: 44 inches.
Time = distance/speed
Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.
Selection A is appropriate.
Answer:
Step-by-step explanation:
<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>
<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!
Wavelength (lambda) = Velocity (v) ÷ Frequency ( 
or Hz )
f = v / (lambda)
f = 3 / 2 = <em>1.5 (Hz)</em>
<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>
Answer:131
Step-by-step explanation:
Answer:
176.625 sq.ft, 4.8 sq.ft
Step-by-step explanation:
Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.
