Please do it on a piece of paper if possible <3

To find the area, we need the height of the triangle first. We already have the base.

Let's find the height (BA)
tan = opposite / adjacent

tan 35 = BA / 12
BA = 12 * tan35
BA = 12 * 0.7002079283708176
BA = 8.402

Area of the triangle = 12*BA/2 = 6*BA = 50.412 square units

What is the approximate diameter of a sphere with a volume of 113 cm^3

larisa86 [58]

Answer:

B. 6 cm

Step-by-step explanation:

$\text{Take the volume of a sphere and solve for r.}\\V=\frac{4}{3}\pi r^3\\\text{We already know that the volume is 113, so substitute that value.}\\113=\frac{4}{3}\pi r^3\\\text{Divide both sides by 4/3 pi.}\\\frac{113}{\frac{4}{3}\pi}=r^3\\\text{Divide 113 by 4/3 pi.}\\r^3=26.98\\\text{For a more accessible value, round up.}\\r^3 \approx27\\\text{Take the cube root of both sides.}\\r=3$

Now that the radius is known, all we have to do is multiply it by 2 to get the diameter. Here the answer is simply 3 * 2, or 6.

frozen [14]

$\text{Solve the equation:}\\\\2x^2-11=87\\\\\text{Add 11 to both sides}\\\\2x^2=98\\\\\text{Divide both sides by 2}\\\\x^2=49\\\\\text{Square root:}\\\\x=\pm\sqrt49\\\\\text{This means that the answer could be 7 or -7}\\\\\boxed{\text{x=7 or x= -7}}$
