The surface area of a sphere with a radius of 12 units is about 1,809.6 units2
Surface area of sphere: 4*pi*12^2 = 576*pi square m
Total surface area = 864 cm2Area of each face = 1/6 of that = 144 cm2Length of the side of the cube = sqrt(144) = 12 cmVolume = 123 = 1,728 cm3
True... Good luck with Apex :)
Surface area: 4*pi*62 = 144*pi square inches Volume: 4/3*pi*63 = 288*pi cubic inches
The surface area of a sphere with a radius of 12 units is about 1,809.6 units2
Surface area of a sphere is: 4*pi*radius squared
Surface area of a sphere = 4*pi*radius^2
Surface area of sphere: 4*pi*12^2 = 576*pi square m
Surface area of the sphere = 4*pi*122 = 1809.557368 square units
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
the formula for surface area of a sphere is 4pi(r squared) so do 4x3.14x144 equals 576 pieunits^2
144pi units squared
Surface area = 4*pi*122 = 576*pi square units
volume is 12x12x12 surface area is 12x12x6
Surface area = 4*pi*12 = 12.566 square units to 3 decimal places
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
