The inside radius of the ball is (half of 22 cm) less 0.5 cm, or 11 cm less 0.5 cm, or 10.5 cm.

The area of the inside surface of the ball is thus

A = 4*pi*r^2, which here is

A = 4*pi*(10.5 cm)^2 = 1385.4 cm^2.

Look below for answer! Have a great day and please mark me brainliest!

Step-by-step explanation:

Bedroom 1: 22x15=330

330x7.25=2392.5

Bedroom 2: 15x12=180

180x7.25=1305

Bedroom 3: 13x12=156

156x7.25=1131

2392.5+1305+1131= 4828.5

Bedroom 1: 22x15=330

330x6.75=2227.5

Bedroom 2: 15x12=180

180x6.75=1215

Bedroom 3: 13x12=156

156x6.75=1053

2227.5+1215+1053+100= 4595.5

Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.
