trasher [3.6K]

can someone help me do this expression 6+(8÷2)-2+(4-1)

<h3><u>SOLU</u><u>TION</u><u> AND</u><u> ANSWER</u><u>:</u></h3>

CALCULATING THE VALUE

Divide first 8 and 2 and subtract 4 - 1

$\large \sf = 6 + 4 - 2 + (4 - 1)$

$\large \sf = 6 + 4 - 2 + 3$

Lastly calculate the sum or difference

$\sf \: calculate \: the \: sum \: of \: the \: positive \: numbers \: \: \large \sf \rightarrow \red{6 + 4} - 2 \red{+ 3}$

$\large \sf = 13 - 2$

$\large \sf = 11$

<h3><u>FINAL</u><u> </u><u>ANSWER</u><u>:</u></h3>

$\huge \orange{ \underline{ \boxed{11}}}$

HOPE THIS HELP YOU! HAVE A NICE DAY!

The volume of the composite figure is 3532.5 cubic inches

<h3>How to determine the volume of the composite figure?</h3>

From the given figure, we have the following dimensions:

Height, h = 15 inches
Radius of small cylinder, r = 5 inches
Radius of large cylinder, R = 10 inches

The volume of a cylinder is

V = πr^2h

So, the volume of the composite figure is

V = πR^2h - πr^2h

Substitute the known values in the above equation

V = 3.14 * 10^2 * 15 - 3.14 * 5^2 * 15

Evaluate the product

V = 3532.5

Hence, the volume of the composite figure is 3532.5 cubic inches
