Area of cylinder curved surface= 2.pi.r.h;
 area of one end = pi.r²

<span>h =  height of cylinder
r = radius of base. </span>

<span>2.pi.r.(50) + pi.r² = 3000. </span>
<span>So: pi.r² + 100.pi.r - 3000 = 0 
</span>its a quardatic equation
<span>The value of r that is > 0 and that satisfies that equation is r = 8.778. </span>
<span>So radius = 8.778 cm
hope this helps</span>

Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).
siniylev [52]

Answer:

Option b Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

A(-4,-2)\\B(-7,-7)

step 1

substitute the values in the formula

d=\sqrt{(-7-(-2))^{2}+(-7-(-4))^{2}}

step 2

Simplify

d=\sqrt{(-7+2)^{2}+(-7+4)^{2}}

step 3

d=\sqrt{(-5)^{2}+(-3)^{2}}

step 4

d=\sqrt{25+9}

step 5

d=\sqrt{34}

therefore

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.
