Mathematics
1 answer:
Wewaii [24]3 years ago
5 0

The circumference of the base is 40 cm, and this equals 2*pi*r. The radius, r, is found as follows:


40 cm

r = ------------ = 6.369 cm. The area of the base, A = pi*r^2, = 3.14*40.570

2(3.14)


The volume here is V = (1/3)(area of base)*(height)


= (1/3)(127.45)(9) cm^3 = 382.36 cm^3 (answer)

A killer whale has eaten 75 pounds of fish today. It needs to eat at least 140 pounds of fish each day.
Alenkasestr [34]

Answer:

a) x ≥ 4.33

b) The killer whale should eat four or five more buckets of fish because eating it will give the required amount of fishes the killer whale is required to eat per day.

Step-by-step explanation:

The killer whale has taken 75 pounds of fish.

It needs to eat at least 140 pounds of fish per day. This means that the whale has at least (140 – 65)= 65 pounds of fish to eat for that day.

a) you Let the count of bucket = x

Each bucket holds 15 pounds of fish

Quantity of 1 bucket * count of bucket = what is remaining for the fish to eat

15x = 65

x = 65/15

x= 4.33

x= 4.33 buckets

At least 4.33 buckets means greater than or equal to 4.33 buckets.

Therefore the count of the bucket is

x ≥ 4.33

b) The killer whale should eat four or five more buckets of fish because eating it will give the required amount of fishes the killer whale is required to eat per day.

I need help understanding how to do the problem
notsponge [240]
So.. if you notice the picture below

is really just 3/4 of a cylinder, or, a full cylinder, and then you slice 1/4 off of it
notice the right-angle in your picture at the bottom, is cut at a right-angle, meaning, the cutout is 1/4 of the volume

so \bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad 
\begin{cases}
r=radius\\
h=height
\end{cases}\qquad \frac{3}{4}\textit{ of that}\implies \cfrac{3}{4}\cdot \pi r^2 h
