Belle made a scale drawing of a mural where 2 inches of the drawing represents 3 feet on the actual mural (scale 2 in. = 3 ft.). In real life, the mural is 6 feet tall and 18 feet wide. What is the area of her drawing in square inches?
Answers
Answer:
Very sorry if this is wrong but, I think the answer would be 48 inches.Step-by-step explanation:
If every 3ft. = 2in. then I believe you would first divide the length and width by 3. So 6 divided by 3 is 2 and 18 divided by 3 is 6. Then you would multiply 2 and 6 by 2 since every 3ft = 2in.

Answers
Answer:
4,605cm
Step-by-step explanation:
You have to find the volume of the cone first (V=πr(2)h/
3). To do that you do 20/2 to get the radious, then you do (3.14)*(10^2)(24/3)=2512. Then you have to find the volume for the hemisphere (V=2/
3(3.14)r^3). Radious still equals 10, so 2/3*3.14*10^3= 2093. Add the two volumes together.
