Answer:
6
Step-by-step explanation:
h = 8
Surface area = 66π
2πr(r +h) = 66π
2πr(r + 8) = 66π
r² + 8r = 33
r² + 8r - 33 = 0
r² + 11r - 3r - 33 = 0
r(r + 11) - 3(r + 11) = 0
(r +11 ) (r - 3) = 0
r - 3 = 0 {Ignore r = -11 as radius will not have negative value}
r = 3
Diameter = 3*2 = 6 units
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)
