Answer 22

step by step explanation

4421.12 = \pi(8 {}^{2})h

\frac{4421.12}{64}  = \pi \frac{64}{64} h

I divided 64 since that's the opposite of multiplying to get h by itself

69.08 = \pi \: h

this could be your answer if you want it as terms of pi but if you say pi is 3.14 then you keep going and divide 69.08 by 3.14 to get h by itself

\frac{69.08}{3.14}  =  \frac{3.14}{3.14} h

then you get the answer

22 = h

hopefully this helps

Wendell is curious how much space Jordan will have inside the doghouse to move around in. What is the volume of the doghouse?
miss Akunina [59]

Answer:

Da answer isssss in the step by step lol *

note: Each length with one mark (I) is 36 inches. Each length with two marks (II) is 18 inches. Each length with three marks (III) is 30 inches. Each end has a height (from the highest point to the lowest point) of 28 inches.

note 2: I might not be right but when I get my work checked ill fix the answer skip to the end for the answer

Step-by-step explanation:

Finding The Volume of The Rectangular Prism

step one: use the images to find the width, height, and length.

the width is 36 in

the height is 18 in

the length is 30 in

step two: multiply the width by height by length aka width*height*length.

So, the volume is 19440 square inches

Finding The Volume Of an Isosceles Triangular Prism

so let us say the slanted lines on the triangular prism are named (a) and the bottom line that completes the forward and back-facing triangle is named (b). (yall probably don't know what I'm talking about lol)

step one: finding the base by using the image the base is the bottom line (b)

base = 36 in

step two: find the height of the base triangle (use your big brain uwu also the height is in found in the images)

height = 10 in

step three: find the depth/height of the triangle (ik is cunfusing ;| )

depth/height = 36 in

step four: now do this confusion formula

(((b*h)/2)*triangle height

((36*10)/2)36 = 6480 square inches

Finishing THEM!!

6480 square inches + 19440 square inches = 25920 square inches.

Answer (25920 square inches)

. Find the surface area of a sphere with diameter 30 m. Leave your answer in terms of
OlgaM077 [116]

The sphere has surface are of 900π m².

Step-by-step explanation:

Given,

Diameter = d = 30m

Radius = \frac{d}{2} =\frac{30}{2} = 15m

Surface area of sphere = 4\pi\ r^2

Surface\ area = 4*\pi *(15)^2\\Surface\ area = 4*\pi * 225\\Surface\ area= 990\pi

The sphere has surface are of 900π m².
