The diameter is 14π
Step-by-step explanation:
We know the area of a circle is πr^2
let 49π=πr^2

Step-by-step explanation:
<u>Volume of the prism is the product of its base area and height</u>
- V = AH
- V = 1260 cm³
- H = 18 cm
<u>Find base area:</u>
<u>Area of the trapezoid:</u>
<u>Substitute given values and solve for h:</u>
- 70 = 1/2(12 + 8)h
- 70 = 10h
- h = 70/10
- h = 7 cm
