Answer:

251.2 in^2

Explanation:

you use the formula given (2πr^2+2πrh)

And you plug in the numbers

2π2^2+2π2×6

then you solve and subtract the 4 bases that are overlapping

301.44-(12.56×4)

and get the answer 251.2 in^2

Garrett is 3 years older than Rachael. In 2 years the sum of their ages will be 39. How old is Garrett now?
ziro4ka [17]
Let garret’s age be x

x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16

Garrett’s age after two years = 16 + 2 = 18

Find the slope-intercept form of the equation of the line through the point (0, -4) and (1, 0).
Arisa [49]

Answer:

The Slope Intercept form of the equation through the point (0, -4) and

(1, 0)  is  y = 4 x - 1

Step-by-step explanation:

Here, the given points are A (0,-4) and B(1,0)

Now, slope of the equation with points (a,b) and (c,d) is given as

m = \frac{d - b}{c -a}

So, here the slope of the line AB is given as:

m = \frac{0 - (-4)}{1-0} = \frac{4}{1}  = 4

⇒ m = 4

Now, by POINT SLOPE  form:

The equation with slope m and point  (x0 , y0) is represented as :

(y-y0)  = m (x-x0)

⇒ The equation of AB is of the form with point (1,0) is

y - 0 = 4 (x -1)

or, y = 4 x - 1

Also, the SLOPE INTERCEPT form of an equation is of the form

y = m x + C ;     m = slope and C =  y -intercept

Hence, the slope intercept form of the equation through the point (0, -4) and (1, 0)  is  y = 4 x - 1
