Answer:
2700
Step-by-step explanation:
the formula is pi r squared, so if r is 30(diameter/2),
and 2700 is the closest to the answer
B I assume, not 100% sure
The gradient function is
y1-y2/x1-x2
So the gradient of this line is
2-0/0-(-5)= 2/5
Recall that the linear line function is
y=mx +c ,
m is the gradient while c is the y-intercept
So, the equation of this line is
y= 2/5x + 2
The new height is 20 in.
Explanation:
Let the width and height of the original triangle be w1 and h1
w1 = 5 in
h1 = 4 in
Let the width and height of the enlarged triangle be w2 and h2
w2 = 25 in
h2 = ?
(Since the triangles are similar, we can use the ratio of the given sides)
h2 / h1 = w2 / w1
h2 / 4 = 25 / 5
h2 / 4 = 5
h2 = 5 x 4
h2 = 20 in
Positive because it’s going into the 1st quadrant where all of the positive numbers are.
