Question 19
5. The radius of the picture and the frame is 30 cm. The radius of just the picture opening is 12 cm. What
is the area of the frame? "Hint...find the area of just the picture
opening and subtract it from the area of
the entire frame and picture.
12cm
30 cm

Answer 1

Step-by-step explanation:

To find the area of the frame, we first need to find the area of the entire frame and picture, then subtract the area of just the picture opening.

Area of entire frame and picture:

= π * (radius of frame)^2

= π * (30 cm)^2

Area of just the picture opening:

= π * (radius of picture opening)^2

= π * (12 cm)^2

Now, we can subtract the area of the picture opening from the area of the entire frame and picture:

Area of frame = Area of entire frame and picture - Area of just the picture opening

= π * (30 cm)^2 - π * (12 cm)^2

Now, you can calculate the numerical value.
