MATH QUESTION!! PLEASE HELP A ganza is a percussion instrument used in samba music.

a. Find the surface area of each of the two labeled ganzas in terms of π , rounded to the nearest thousandths and as a decimal, round to the nearest whole number.

Surface area of smaller ganza =
π≈
cm2
Surface area of larger ganza =
π≈
cm2
b. The weight of the smaller ganza is 1.1 pounds. Assume that the surface area is proportional to the weight. What is the weight of the larger ganza to the nearest tenth of a pound?

The weight of the larger ganza is about
pounds.

bro i literally had the same question about this

you in honors or something? sry i only got A

I might have B later on or something

A.

41.125π ≈ 129

149.875π ≈ 471

Step-by-step explanation:

Surface area of smaller ganza:

3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325

1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)

Surface area of larger ganza:

5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925

2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)

π

129/3.14 = 41.125

471/3.14 = 149.875

A.

41.125π ≈ 129

149.875π ≈ 471

B) 4.0 lbs.

Step-by-step explanation:

Surface area of smaller ganza:

3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325

1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)

Surface area of larger ganza:

5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925

2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)

π

129/3.14 = 41.125

471/3.14 = 149.875 (Going off of what the other guy said.)

(B) 4.0

129/1.1 = 117.272727273

Divide that from 471.

471/117.272727273 = 4.016

4, But they want you to round to the nearest tenth so it is 4.0 :)

the correct answer is x/3+10≥32

hope this !

the answer is 48m^2!
