Answer 1

Answer(23).

75.0 mi/hr = 75*.447 = 33.25 m/s^2

1 mi/hr (mi hr-1) = 1.47 ft/s (ft s-1) = 1.61 km/hr (km hr-1) = 0.447 m/s (m s-1)

Answer(25).

Given diameter of sphere = 5.36 inches

= 5.36 * 2.54 centimetres (because 1 inch = 2.54 centimetres)

= 13.6144 centimetres

Radius of sphere = diameter/2

= 13.6144/2 centimetres

= 6.8072 centimetres

Surface area of sphere = 4*pi*radius*radius

= 4 * (22/7) * 6.80 * 6.80 square centimetrs

= 581.30 square centimetres

Volume of sphere = (4/3) * pi * radius * radius * radius

= (4/3) * (22/7) * 6.80 * 6.80 * 6.80 cubic centimetres

= 1317.619 cubic centimetres
