OpenStudy (anonymous):

radius of 60 m 3,600 m2 7,200 m2 14,400 m2 1,800 m2

OpenStudy (anonymous):

Formula: S=4(pi)r^2

OpenStudy (anonymous):

so, S=(4)(3.14)(60^2)

OpenStudy (anonymous):

60^2=3600, so, S=45,216

OpenStudy (anonymous):

How would the answer be put into pi ?

OpenStudy (anonymous):

45,216/3.14=14,400

diameter of 14 cm

OpenStudy (anonymous):

S=4(pi)7^2 7^2=49 S=(4)(3.14)(49) S=615.44 to get answer in pi, 615.44/3.14=196
