Answer:
54m2
Step-by-step explanation:
Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.
Taking area of first one=24m2,then area of the second =30m2.
To get area of whole shape, we add both areas=54m2
NB:Area=l×b
I don't know how to explain but the answer is 2.4.
Answer:
8
Step-by-step explanation:
Answer:
a. 45 π
b. 12 π
c. 16 π
Step-by-step explanation:
a.
If a 3×5 rectangle is revolved about one of its sides of length 5 to create a solid of revolution, we can see a cilinder with:
Radius: 3
Height: 5
Then the volume of the cylinder is:
V=π*r^{2} *h= π*(3)^{2} *(5) = π*(9)*(5)=45 π
b. If a 3-4-5 right triangle is revolved about a leg of length 4 to create a solid of revolution. We can see a cone with:
Radius: 3
Height: 4
Then the volume of the cone is:
V=(1/3)*π*r^{2} *h= (1/3)*π*(3)^{2} *(4) = (1/3)*π*(9)*(4)=12 π
c. We can answer this item using the past (b. item) and solving for the other leg revolution (3):
Then we will have:
Radius: 4
Height: 3
Then the volume of the cone is:
V=(1/3)*π*r^{2} *h= (1/3)*π*(4)^{2} *(3) = (1/3)*π*(16)*(3)=16 π
Answer:
1. Median refers to the central value of a collection of data
Therefore it is 73.4
2. Mode refers to the frequency of a value in a collection of data
It will be 49 as it is repeated 2 times
3. Range refers to The greatest number subtracted from the smallest number
Which will be 90-49=41
Hope this helps dude!
