Answer:
3057.6 cm³
Step-by-step explanation:
You have a cylinder and a rectangular prism. Solve for the area of each separately.
<u>Cylinder</u>
The formula for volume of a cylinder is V = πr²h. The radius is 7, and the height is 7.
V = πr²h
V = π(7)²(7)
V = π(49)(7)
V = 343π
V = 1077.57 cm³
<u>Rectangular Prism</u>
The formula for volume of a rectangular prism is V = lwh. The length is 20, the width is 11, and the height is 9.
V = lwh
V = (20)(11)(9)
V = (220)(9)
V = 1980 cm³
Add the areas of the two shapes.
1077.57 cm³ + 1980 cm³ = 3057.57 cm³
Round to the nearest tenth.
3057.57 cm³ ≈ 3057.6 cm³
If b was 3 a will be 6 because 2*3=6
and for the second part b will be 3.5 because 2*3.5=7
0.04 is 1/10 of 0.4
0.4 x 0.10 = 0.04

First of all, half of 18 is 9, and if you divide 18 by 2.5, it results in 7.2. I hope this helps!
