Step-by-step explanation:
Let's say R is the initial radius of the sphere, and r is the radius at time t.
The volume of the sphere at time t is:
V = 4/3 π r³
Taking derivative with respect to radius:
dV/dr = 4π r²
This is a maximum when r is a maximum, which is when r = R.
(dV/dr)max = 4π R²
This is 4 times the sphere's initial great circle area, but not the great circle circumference. The problem statement contains an error.
The answer is if you tilt it a little bit it looks like a kite and if you look on the web a rhombus kinda looks like a kite and plz mark me brainiest because you know you looked for answers on the web
Answer:
A) 41.9
Step-by-step explanation:
The formula I use is π(pi)r(radius)^2h(height)/3, so it looks like πr^2(h/3) and I used that and I got 41.88 which rounds to 41.9 or A
Answer: i didnt understand the answer choice but the correct answer is 48/12=width. width=4
Step-by-step explanation:
as we know the area of a rectangle is area=length X width
so we plug in 48 as area and 12 as length
48=12 x width
48/12=width(divide both sides by 12)
Answer:
8 records were sold on Wednesday, and 24 records were sold on Thursday
Step-by-step explanation:
Let's call the number of records sold on Wednesday w, and the number sold on Thursday t.
t+w=32
t=3w
Substituting:
(3w)+w=32
4w=32
w=8
t=3w=3(8)=24
Hope this helps!
