If pi=3.1416, then 6×3.1416=18.8416
you said 4 pi times 6 to the second power.thats 452.38934236
The formula for working out the circumference is 2pi x radius, aka pi diameter. The radius is 6 so times this by 2 and then pi. The answer would be: (6 x 2) x pi = 12 x pi = 37.69911184. Pay attention in maths lessons next time! ;) Hope this helps.
The circumference of a circle with a 6-inch diameter is 18.85 inches. (C = d x Pi).
288 pi cm cube root = 4/3(that's a fraction)*times* pi *times* radius cube root288 *divided by* 4/3 = 216.00000000000000000000000000001cube square root 216.00000000000000000000000000001 and you should get a simple 6
If pi=3.1416, then 6×3.1416=18.8416
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.

Volume of sphere: 4/3 times pi times 6 cubed = 288*pi cubic inches
mass of proton is 6 x pi raised to power 5 times mass of electron
Surface area of a sphere equals 4 times Pi times the Square of its radius. So plugging in the needed radius of 6 makes the formula Area=4*pi*R^2 or 4*pi *6^2 or 4*36*pi and with pi=3.141592654... this becomes 452.3893421... units (144*3.141592654...)
Circumference of a circle is pi times diameter therefore C = pi(3.14159265359) * 6 = 18.84955592154 say 18.85 inches (3.14159265359 is the approximate value of pi)
The circumference ( C ) of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. Given that the diameter is 6 cm, the circumference is ( C = \pi \times 6 ) cm. Therefore, the circumference of the circle is ( 6\pi ) cm.
The area of a circle is pi times radius times radius. 6 cm = 2 times 3 cm radius = 3 cm. SO, pi times 3 cm times 3 cm 9 pi pi is approximately 3.141592... 9 times 3.141592... is 28.274328...
To find the surface area of a right cone, use the formula ( SA = \pi r (r + l) ), where ( r ) is the radius and ( l ) is the slant height. Given ( r = 2 ) and ( l = 6 ), the surface area is ( SA = \pi \times 2 \times (2 + 6) = \pi \times 2 \times 8 = 16\pi ). Therefore, the surface area of the cone is ( 16\pi ) square units.
The total surface area ( A ) of a right cone is given by the formula ( A = \pi r (r + l) ), where ( r ) is the radius and ( l ) is the slant height. Substituting the values ( r = 6 ) inches and ( l = 10 ) inches, we get: [ A = \pi \times 6 \times (6 + 10) = \pi \times 6 \times 16 = 96\pi , \text{square inches}. ] Thus, the total surface area of the cone is approximately ( 301.59 ) square inches (using ( \pi \approx 3.14 )).
