Look at the picture.

ΔABC and ΔBDC are <span>equilateral triangles.

Area of sector of a circle:
\dfrac{60^o}{360^o}=\dfrac{1}{6}\\\\area\ of\ a\ circle\\A_O=\pi r^2;\ r=4\\A_O=\pi\cdot4^2=16\pi\\\\A_s=\dfrac{1}{6}A_O\to A_s=\dfrac{1}{6}\cdot16\pi=\boxed{\dfrac{8}{3}\pi}

Area of the triangle ABC:
A_\Delta=\dfrac{a^2\sqrt3}{4};\ a=4\\\\A_\Delta=\dfrac{4^2\sqrt3}{4}=\dfrac{16\sqrt3}{4}=\boxed{4\sqrt3}

Area of the shaded portion:
A=2(A_s-A_\Delta)\\\\\boxed{A=2\left(\dfrac{8}{3}\pi-4\sqrt3\right)\approx2.89}

How do you use cos on the calculater in math
Veronika [31]

Answer:First make sure your calculator is on the right setting which would be a DEG. Then depending on the problem you would press COS, put whats needed inside the parentheses and close it.

Or if a different kind of problem you would press 2nd on the top of the calculator then Cos and continue the same way as the first one.

Solve for r: C = 2(pi)r.
Masja [62]
<span>the main condition can be found one of the following given methods: if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B in our case we have C = 2*Pi* R, solve for R does mean, searching the value of R, so if we want to find the value of R, it is R = C / 2*Pi </span>
