Explicación paso a paso:

R = 13cm

P = 3.14 x 26 =81.64cm

A = 3.14 x 13^2 = 530.66cm2

D = 34cm

P = 3.14 x 34 = 106.76cm

A = 3.14 x 17^2 = 907.46cm2

R = 12cm

P = 3.14 x 24 = 75.36cm

A = 3.14 x 12^2 = 452.16cm2

R = 9m

P = 3.14 x 18 = 56.52m

A = 3.14 x 9^2 = 254.34m2

D = 4m

P = 3.14 x 4 = 12.56m

A = 3.14 x 2^2 = 12.56m2

D = 40m

P = 3.14 x 40 = 125.6m

A = 3.14 x 20^2 = 1256m2

R = 45mm

P = 3.14 x 90 = 282.6mm

A = 3.14 x 45^2 = 6358.5mm2

R = 15mm

P = 3.14 x 30 = 94.2mm

A = 3.14 x 15^2 = 706.5mm2

D = 36mm

P = 3.14 x 36 = 113.04mm

A = 3.14 x 18^2 = 1017.36mm2

R = 25mm

P = 3.14 x 50 = 157mm

A = 3.14 x 25^2 = 1962.5mm2
