Answer:
1st angle = X
2nd angle = X + 7
3rd angle = X + 18
Then (sum. them): 3X + 25 = 180 ==> X = 51.67 degree
Therefore,
1st angle = 51.67 degree
2nd angle = 58.67 degree
3rd angle = 69.67 degree
Answer:
Area: 201.06
Circumference:50.26
Step-by-step explanation:
Area of a circle: pi*r^2
8^2=8*8=64
64*pi=201.06193 Rounded to the neares hundredth=201.06
_________________________________________________
Circumference of a circle: 2pi * r
2*8=16
16*pi=50.2654825 Rounded to the nearest hundredth = 50.26
Answer:
the volume of the sphere is

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere and cube.
Given data
Volume of cube v = 64 cubic inches
since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,
we know that volume of cube is expressed as



![l= \sqrt[3]{64}](https://tex.z-dn.net/?f=l%3D%20%5Csqrt%5B3%5D%7B64%7D)

also diameter d=length l
Diameter d=
Radius r =
=
= 
Height h=
we know that the volume of a sphere is given by

substituting into the formula we have

Answer:
One
Step-by-step explanation:
A, B, R and C lie on the same plane, while the others do not
Prism A has a volume of 36 m
Prism B has a volume of 288 m
The ratio of there lengths is that for every 1m in prism A, there are 8 m in prism B
