What is the volume of a hemisphere with a radius of 4.9 ft, rounded to the nearest
tenth of a cubic foot?
Answers
The volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.
Hemisphere
A hemisphere is gotten when a sphere is cut into two equal halves.
The volume of a hemisphere is expressed as;
V = (2/3)πr³
Where r is the radius and π is pi ( π = 3.14 )
Given the data in the question;
Radius of the hemisphere r = 4.9ftVolume of the hemisphere V = ?To determine the volume of the hemisphere, we substitute our values into the expression above.
V = (2/3)πr³
V = (2/3) × π × (4.9ft)³
V = (2/3) × π × 117.649ft³
V = 246.4ft³
Therefore, the volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.

The translation rule will be (x+8 , y+4).
What is Transformation?A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.
The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.
Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.
Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).

A swim instructor would like to test the effect of a new swim technique versus the standard technique for a group of 25 competitive swimmers.
The swim instructor divides the students by class (junior or senior), and then randomly allocates half of the 14 juniors and 5 of the 11 seniors to receive instruction on the new technique.
During swim practice, the instructor times the juniors as they race against each other to see if those who learned the new technique outperform their peers. The instructor does the same for the seniors.
At the end of practice, the instructor compares the average swim time for both juniors and seniors among those who did and did not use the new technique.
A) The instructor should place the 25 student names on slips of paper and place them in a hat. Twelve of the slips should be drawn out and those students should receive the instruction on the new technique.
B) The instructor should place the names of the 14 juniors on slips of paper and place them in one hat. The 11 seniors’ names should be placed on slips of paper and placed into a separate hat. The instructor should randomly select 7 juniors and 5 seniors to receive instruction on the new technique.
C) For each student, the instructor should flip a coin. If the coin lands on heads, the student will receive instruction on the new technique. If the coin lands on tails, the student will not receive instruction on the new technique.
D) The students should line up alphabetically and count off by 2s. Every student who gets a 1 will receive instruction on the new technique. Every student who gets a 2 will not receive instruction on the new technique.

A = ?
Answers
Answer:
A = 5,752.60
Step-by-step explanation:
P = $3,500
r= 5%
t = 10
k = 4
A = P(1 + r/k)^kt
= 3,500(1 + 0.05/4)^4*10
= 3,500(1 + 0.0125)^40
= 3,500(1.0125)^40
= 3,500(1.6436)
= 5,752.6
