Answer:

8 / sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan A = BC / AC

tan 30 = BC / 8

8 tan 30 = BC

8 * sqrt(3)/3 = BC

8/3 sqrt(3) = BC

Answer:

I think the answer would be the very first one.

they all need to have '' ( ) '' in them.

if a number is outside of that, it needs to at least have a letter beside the number

here's an example

Factored form:

2x(x + y)

Answer:

The radius of the sphere, to the nearest cm:

r\approx 20 cm

Step-by-step explanation:

The surface area of a sphere is given by the formula

A = 4πr²

where r is the radius of the sphere.

Given

  • The surface area of sphere A = 5024 cm²

The radius of the sphere can be determined such as

A\:=\:4\pi r^2

r\:=\:\frac{1}{2}\sqrt{\frac{A}{\pi }}

Plug in Surface Area of sphere =  5024, π = 3.14 in the formula

\:r\:=\:\frac{1}{2}\sqrt{\frac{5024}{3.14}}\:\:

r\approx 20 cm

Therefore, the radius of the sphere, to the nearest cm:

r\approx 20 cm
