Answer:

☆》 ANSWER 《☆

GIVEN :

CIRCUMFERENCE = 870 M

TO FIND :

AREA REQUIRED FOR THE PLANETARIUM .

PROOF :

$circumference = 2r\pi \\ 870 = 44 \div 7 \times r \\ r = 870 \times 7 \div 44 \\ r = 318.40 \: m$

THEREFORE ;

$area \: = \pi {r}^{2} \\ = 3.14 \times {318.40}^{2} \\ = 60145.34 \: {m}^{2}$
