Can someone help me please ​
bogdanovich [222]

Answer:

1921.67

1922 to the nearest whole number

Step-by-step explanation:

Cylinder

V = pi*r^2 * h

pi = 3.14

r = d/2

r = 12/2

r = 6

h = 13

V = 3.14 * 6^2 * 13

V = 1469.52

1/2 Sphere

V= 2/3 * pi * r^3

r = 6

pi = 3.14

V = (2/3) 3.14 * 216

V = 452.2

Total Volume

V_tot = 452.2 + 1469.52

V_tot = 1921.67

A circle with area 81ㅠ has a sector with a central angle of 120°.
Mrac [35]

Answer:

<h2>84.78</h2>

Step-by-step explanation:

We have the area of a circle

A_O=81\pi

The sector with a central angle of

120^o

Calculate, what part of 360° is an angle 120°:

\dfrac{120^o}{360^o}=\dfrac{1}{3}

The same part of an area of a circle is an area of a segment.

Therefore:

A_S=\dfrac{1}{3}\cdot81\pi=27\pi

Use π ≈ 3.14

A_S\approx(27)(3.14)=84.78

E. 15

I. 39°

F. 71°

C. 25.6

H.12.9

K.55°

Step by Step Explanation:

1. cos^{-1}(52/56)=21.7867893 or 22 degrees

2. 22sin43=15

3. tan^{-1}(34/42) or 38.990999404 or 39 degrees

4. sin^{-1}(51/54)=70.81186355 or 71 degrees

5. 20/(tan38)=25.58883264 or 25.6

6. 20sin40=12.85575219 or 12.9

7. cos^{-1}(26/45)=54.70560532 or55 degrees
