Answer:

1) D. 14 cm

2) C. 43.96 cm

Step-by-step explanation:

First answer explanation:

Segment A to B would be 14 cm because the radius (middle to the bounding surface) is 7 cm so you just have to double that since you want to go from one side point to the other crossing through the middle.

The first answer is D.

Second answer explanation:

The circumference is basically the perimeter of a circle. To find the circumference you have to do 2pr (2*pi*radius). We know that the radius is 7 cm and pi is 3.14. Now we can plug the numbers in, 2*3.14*7 is the equation we have to solve. First we'll do 2*7 and get 14. Next we do the final step 3.14*14. We know that it has to be either A or C at this point because the other numbers are too low and if you think about it the answer has to be a decimal so it has to be C. If you want to do the multiplication that is fine but it is unnecessary.

We know that

the scale is is 1/2 inch = 4 feet

using a graph tool
the approximate measurements in the drawing are
5 cm x 4 cm
convert to in
5/2.54--------> 1.97 in
4/2.54------> 1.57 in

convert drawing to actual
if 0.5 in---------> 4 ft
1.97in-------> X
X=1.97*4/0.5------> X=15.76 ft

if 0.5 in---------> 4 ft
1.57 in-------> X
X=1.57*4/0.5------> X=12.56 ft

the approximate area of Quinto's bedroom is 12.56*15.76=197.95 ft²

the answer is
the option C)192 ft²
