Answer: See explanation

Explanation:

I've attached the mathematics question that you posted.

The first picture is a cone. The surface area of a cone is:

= πrl + πr²

where,

π = 3.14

r = diameter/2 = 9m/2 = 4.5m

l = 13m

Surface area = πrl + πr²

= (3.14 × 4.5 × 13) + (3.14 × 4.5²)

= 183.69 + 63.585

= 247.275m²

The second picture is a hemisphere.

Volume of a hemisphere = 2/3πr³

= 2/3 × 3.14 × 3³

= 2/3 × 3.14 × 27

= 56.52km³

Surface area of a hemisphere = 3πr²

= 3 × 3.14 × 3²

= 3 × 3.14 × 9

= 84.78km²
