Answer:
33.51 cm
Step-by-step explanation:
240/360 = 2/3 (Arc length is 2/3 of the total circumference)
C = 2
r ( Calculate the total circumference)
C = 2(8)
C = 50.265
2/3(50.265) (Take 2/3 of the circumference. times 2 divide by 3)
33.51
Use a calculator and leave the answer to C and then multiply and divide. You get a more precise answer.
Answer:
show the image because we cant answer it if there's no picture or image
Step-by-step explanation:
The surface area of a cylinder is the sum of the top + bottom + body, right?
The top and the bottom are circles with the same radius 3.5 . And we know that the area of a circle is r^2pi, (don't forget we have 2 circle, so, the answer must be multiplied by 2)
Now, the body: the body is just a rectangular with the width is the height of the cylinder and the length is the circumference of the circle.
The circumference = 2 r pi
the height is given
All you need to do is to calculate them and add them up. You need to work out to get the answer.
it is not linear because it does not have a constant rate of change
Answer:
a:30 b:70 c:80
Step-by-step explanation:
triangle= 180*
3:7:8= 180*
7+3+8= 18
180/18= 10
a= 3x10= 30*
b=7x10= 70*
c=8x10= 80*
