A line has no width nor depth, so it has no surface, thus its surface area is 0 cm2
Area=1/2bh=1/2x15x6.5=48.75 sq cm
1,278
2*pi*r*h=area of curved surface 377=2*3.1428*r*15 r= 4cm Volume=pi*r*r*h 3.1428*16*15 754.27 cubic cm
Surface area of a sphere (the golfball) = 4*pi*radius2 square cm
The curved surface area is 904.78cm2
Total surface area = (2*pi*62)+(12*pi*15) = 791.681 square cm to 3 d.p.
The answer will depend what the 6 cm and 15 cm are measures of.
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
Area=1/2bh=1/2x15x6.5=48.75 sq cm
1,278
2*pi*r*h=area of curved surface 377=2*3.1428*r*15 r= 4cm Volume=pi*r*r*h 3.1428*16*15 754.27 cubic cm
Volume does not, surface area does.
The answer is 36π or approximately 113.1 cm.
The curved surface area is 75.4cm2
The curved surface area is 904.78cm2
Surface area of a sphere (the golfball) = 4*pi*radius2 square cm
The area of square is : 225.0
