Answer 1

32.5cm
`^(2)`

Explanation:

A= (7) (9) = 63 / 2

A= 32.5cm
`^(2)`

Answer 2

about 703.69

Explanation:

To calculate the base you would use pi radius squared: 153.93

Since you have 2 bases you would multiply that by 2: 307.87

Then you need to find the circumference (2 pi radius) : 43.98

Then you multiply the circumference by the height: 395.82

Add the bases and the sides to get 703.69
