Answer:
188 meters cubed
Step-by-step explanation:
- radius = 1/2d d=6 radius =3 height 20
- formula for thia equation is 1/3 (3.14)(3^2)(20)
- (3.14)(9)(20)
- 3.14 x 9 = 28.26
- 28.26 x 20 = 565.2
- 565.2/3 = 188.40
- 188.4 round to 3sf is 188
Answer:
A,A,D
Step-by-step explanation:
>The order of the letters are very important ΔMAX≅ΔKFC
Draw on a paper 2 triangles and label them starting in the same corresponding place and in the same order to find the corresponding parts.
4)
A F
M . X . ≅ . K . C
so ∡X≅∡C, answer is A
5)
O A
D . R ≅ . M . T
TM ≅ RD, answer is A
6)
O . A
D . H ≅ R E
so DH ≅ RE, answer D
Answer:
This is a right triangle.
Step-by-step explanation:

Answer:
a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2
b) 120°
c) sin = -1/2 = -30° or 330° both are same
Use the trig circle which i have included in the answer to better understand trig angles
hope that answers your question
I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.
good luck!!
11^2=121
12^2=144
You can write either 11 or 12.
