45 degrees or 0.785398163. The first part is pi radians divided by 4, not quite the same thing.
Volume is 4/3 pi*radius*radius*radius 3.14 times 7 times 7 times 7 times 4 divided by 3= volume 1436.2666666 Surface area is 4 * pi * radius * radius 4 times 3.14 times 7 times 7=surface area 615.44
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
A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)
25.7831 (to 4 dp)
you said 4 pi times 6 to the second power.thats 452.38934236
Circumference = Pi (3.14) times Diameter (C=pD) Diameter = 2 times the Radius (D=2R) or Circumference divided by Pi Area = Pi times the radius squared (A=pr2) So, 4 / 3.14 = 1.27. The diameter of a 4mm nail is 1.27mm.
As tan(x)=sin(x)/cos(x) and sin(pi/4) = cos(pi/4) (= sqrt(2)/2) then tan(pi/4) = 1
