I see it’s asking you how you can find the volume of a hemisphere on question 1. Which would be V = (2/3)πr.
The volume of a hemisphere = (2/3)πr3 cubic units. Where π is a constant whose value is equal to 3.14 approximately. “r” is the radius of the hemisphere. volume of a cone is 1 3 π r 2 h \frac { 1 } { 3 } \pi r ^{ 2 } h 31πr2h, where r denotes the radius of the base of the cone, and h denotes the height of the cone. formula to find the volume of a hemisphere is 2TTr3 / 3, where pi is 3.14, and the radius is half of the diameter.
Since you have a width of 30 ft, I’m guessing 30 x 10 divided by half of 3.14. I hope this helped ! Please leave a brainliest mark and a thanks (:

Han can run 100 meters in 20 seconds how long will it take him to run 3000 metres
Juliette [100K]

Answer:

600 seconds

Step-by-step explanation:

In this case we have to calculate the speed;

Speed = Distance/Time

Speed = 100/20 = 5 mph

Next to get our answer we have to calculate the amount of time

Time = Distance/Speed

Time = 3000/5 = 600 seconds

Total of 49 1/4 + 3 3/8
Ede4ka [16]
49*4=196+1=197/4 
<span>8*3=24+3=27/8 </span>

<span>then make the denominator the same</span>
<span>multiply 197*2 and 4*2 = 394/8 </span>
<span>then 394/8 +27/8 =421/8 </span>
<span>u can either leave it here or in decimal form which would be 52.625 or in mixed numbers-52 5/8</span>
