How do you solve for h? <br> Having trouble with #45

Thepotemich [5.8K]

$S=2\pi r h+2\pi r^2\\
2\pi rh=S-2\pi r^2\\
h=\dfrac{S-2\pi r^2}{2\pi r}\\
h=\dfrac{S}{2\pi r}-1$

Can I get help on this question? Please explain the process of how to solve it too.

Answer:

x = 13

y = 18.38

Step-by-step explanation:

tan 45 = x/13 (tangent = opposite / adjacent)

1 = x/13

multiply both sides by 13

x = 13

cos 45 = 13/y (cosine = adjacent / hypotenuse

0.7071 = 13/y

multiply both side by y

0.7071y = 13

divide both side by 0.7071

y = 18.38

The two bases of a trapezoid are 3 and 11 and the altitude is 8 . What is the area of the trapezoid?

cluponka [151]

We are given two bases as 3 and 11

altitude is 8

formula for area of trapezoid is given by

$A=\frac{a+b}{2} *h$

here a and b are two bases and h is height

plugging the given values we get

$A=\frac{11+3}{2} *8$ =56

Area of trapezoid = 56 unit square
