Answer:
301.59
Step-by-step explanation:
V=1/3hπr²
sorry in advance if its wrong, this is my 1st time answering this type of question. that's what i got for the answer
Pentagons are and example.
1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2
3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2
5) now u ca do it

Question:Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)
2 Answers:
1: y=x+4
2:
answer would be “y=4”
to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)
plug it in to get: (4-4 / 1- -3) = 0/4 = 0
this means the slope would be 0
if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:
you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:
y-4 = 0 (x - -3) or y-4 = 0(x-1)
it doesn’t matter which coordinates you use..
then solve the point slope for slope-intercept.
y-4 = 0(x-3) multiply 0 with x and -3
y-4 = 0x move -4 to the right by adding 4
y = 0x + 4 or y = 4 would be your answer!
Since y=x+3 (given)
Put value of y in equation x+y=(-3)
x+x+3=(-3)
2x=(-6)
x=(-3)
Put x=(-3) in x+y=(-3)
(-3)+y=(-3)
y=0
So, x=(-3)
y=0
