Solve for h SA = 2pir^2 + 2pirh

1 answer:

3 0

SA = 2πr² + 2πrh

• Factorize right side

SA = 2πr(r² + h)

• Divide both sides by 2πr

SA/2πr = r² + h

• Move r² to left side

h = r² - (SA/2πr)

Alejandra correctly wrote the equation y – 3 = y minus 3 equals StartFraction 1 Over 5 EndFraction left-parenthesis x minus 10 r

Delvig [45]

Answer:

y – 3 = 2(x – 10)

Step-by-step explanation:

In point-slope form, the equation is written ...

y -k = m(x -h) . . . . . . . for line with slope m through point (h, k)

If only the slope changes, only the value just outside parentheses changes. When the point is (10, 3) and the new slope is 2, the new equation is ...

y -3 = 2(x -10)
