949 rounded to the nearest ten

Answers

Answer 1

Answer:
949 rounded to the nearest ten would be 950 because 5 and above rounds up to the next 10.

Answer 2

Answer: 950 because round up when its 6or more and down when its 5 or less like 367 seven is more than 5 so you go up to 370 rounded to the nearest ten

Which expression is equivalent to 11(17 – x)?A.

11 • 17 – 11x

B.

17 – 11x

C.

11 • 17 – x

D.

11 + 17 – x

Answers

The answer is A. 11 x 17 - 11x because you would use the distributive property and multiply the number on the outside (11) by everything on the inside (17 and -x)

for this, they are asking you to multiply both 17 and -x by 11. B and C only multiply one term by 11, and D doesn't multiply at all. A is the only one that fits!

Question :-

A cylinder has a diameter of 4 cm and a height of 8.2 cm. What is the surface area of the cylinder?

Answer :-

The surface area of the cylinder is 128.112 cm². Thus, the 2nd option, B makes it as the correct answer.

$\rule{180pt}{3pt}$

Diagram :-

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{2 \: cm}}\put(9,17.5){\sf{8.2 \: cm}}\end{picture}$

Solution :-

As per the provided information in the given question, we have been given that the diameter of the cylinder is 4 cm. Thus, the radius of the cylinder is 2 cm. The height of the cylinder is 8.2 cm. We have been asked to find or calculate the surface area of the cylinder.

To calculate the surface area of the cylinder, we will use the formula below :-

$\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh \:\:}}$

Substitute the given values into the above formula and solve for surfacearea:

$\sf:\implies Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(2 \: cm)^2 + (2)(3.14)(2 \: cm)(8.2\:cm)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(4 \: cm^2) + (2)(3.14)(16.4\:cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(12.56 \: cm^2) + (2)(51.496 \: cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = 25.12 \: cm^2 + 102.992 \: cm^2$

$\sf:\implies \bf{Surface \: Area_((Cylinder)) = 128.112 \: cm^2}$

Therefore :-

The surface area of the cylinder is 128.112 cm². Thus, the 2ndoption, B makes it as the correctanswer.
