Answer:

Volume of composite is 483  mm^3

Step-by-step explanation:

We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):

Volume of the prism = 7 x 12 x 3 mm^3  = 252 mm^3

Volume of the semi-cylinder =  \frac{\pi\,\,R^2\,\,H}{2}  =  \frac{\pi\,\,(3.5)^2\,\,(12)}{2} =230.907 \,\,mm^3

Therefore the sum of both volumes gives:

(252 + 230.907) mm^3 = 482.907  mm^3

WHich can be rounded to the nearest whole number as: 483 mm^3

According to the rule of 72, if Gina invests $100, $500, and $1000 into three separate accounts with the same interest rate, whi
Makovka662 [10]
Let's say the APR is 5%. That means you get 5% of your balance back every year. The $100 balance would get $5 back, the $500 balance would get $25 back, and the $1000 balance would get $50 back. Therefore, all of the balances would take the same amount of time to double, and it would take all of them 20 years.

$5*20 years=$100
$25*20 years=$500
$50*20 years=$1000
