we are given
radius is 3370 mm
![r=3370mm](https://tex.z-dn.net/?f=%20r%3D3370mm%20)
and shape is sphere
so, we can use surface area of sphere formula
![S=4\pi r^2](https://tex.z-dn.net/?f=%20S%3D4%5Cpi%20r%5E2%20)
now, we can plug value of r
![S=4\pi (3370)^2](https://tex.z-dn.net/?f=%20S%3D4%5Cpi%20%283370%29%5E2%20)
now, we can solve for S
and we get

Answer:
See explanation
Step-by-step explanation:
(i) Consider triangles ABC and ADC. In these triangles:
- given;
- given;
- reflective property.
So,
by SAS postulate.
(ii) Congruent triangles have congruent corresponding parts:
(a) ![\angle ABC=\angle ADC](https://tex.z-dn.net/?f=%5Cangle%20ABC%3D%5Cangle%20ADC)
(b) ![\angle ACD=\angle ACB](https://tex.z-dn.net/?f=%5Cangle%20ACD%3D%5Cangle%20ACB)
(c) Line segment AC bisects
and ![\angle BCD.](https://tex.z-dn.net/?f=%5Cangle%20BCD.)
