Answer:

5.29 units

Step-by-step explanation:

By Pythagoras theorem:

${6}^{2} + {x}^{2} = {8}^{2} \\ 36 + {x}^{2} = 64 \\ {x}^{2} = 64 - 36 \\ {x}^{2} = 28 \\ x = \sqrt{28} \\ x = 5.29150262 \: units \\ x \approx 5.29 \: units$

Use the net to find the lateral area of the cylinder. Give your answer in terms of pi.

Zinaida [17]

<u>Answer:</u>

The correct answer option is 153 $\pi mm^2$ .

<u>Step-by-step explanation:</u>

We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.

We know that the formula of the lateral area of a cylinder is given by:

Lateral area of cylinder = $2 \pi r h$

Substituting the given values in the formula to get:

Lateral Area = $2\pi *4.5*17$ = 153 $\pi mm^2$

Match each polynomial to the term that does not change the polynomial's classification when added to it.

Papessa [141]

1) If we add - x to x² + 3 x we will get: x² + 3 x - x = x² + 2 x, with same number of terms and same degree (2),
2 ) xy - 1 + xy = 2 xy - 1
3 ) x + y - 3 y = x - 2 y
4 ) x³ - 5 x² + 1 - 2 x³ = - x³ - 5 x² + 1
Pairs :
( x² + 3 x) ↔ ( -x )
( xy - 1)↔ ( xy )
( x + y ) ↔ ( - 3 y )
( x³ - 5 x + 1 ) ↔ ( - 2 x³ )
