Answer: the answer should be 7

Step-by-step explanation: V=πr2h

3=π·1.52·3

3≈7.06858

you can find the radius for the area of the base 7 by dividing by $\pi$ like such 7/3.1459 the squared because remember its in r2 form which give you 1.5 then plug this in for one of two ways to solve A· $\pi$ 1/3 or V=πr2h

Write the following quadratic in standard form. Then identify a, b, and c. y² - 7y + 6 = -6

Charra [1.4K]

Answer:

Therefore,

$y^{2}-7y+12=0$ ....Standard form.

$a=1\\b=-7\\c=12$ ......Numerical Coefficients.

Step-by-step explanation:

Given:

$y^{2}-7y+6=-6$

To Find:

a ,b , c

Solution:

Quadratic:

A quadratic equation is an equation of the second degree.

Meaning it contains at least one term that is squared.

The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

Here it is given as

$y^{2}-7y+6=-6$

Adding 6 on both the side we get

$y^{2}-7y+6+6=-6+6$

$y^{2}-7y+12=0$

Which is Quadratic Equation in STANDARD form Where,

$a=1\\b=-7\\c=12$

Therefore,

$y^{2}-7y+12=0$ ....Standard form.

$a=1\\b=-7\\c=12$ ......Numerical Coefficients.
