90° is equal to 
or 1.5707 radians.
Step-by-step explanation:
Step 1:
If an angle is represented in degrees, it will be of the form x°.
If an angle is represented in radians, it will be of the form 
radians.
To convert degrees to radians, we multiply the degree measure by 
.
For the conversion of degrees to radians,
the degrees in radians = (given value in degrees)().
Step 2:
To convert
90°,
radians.
So 90° is equal to or 1.5707 radians.
Answer:
The number will be 
Step-by-step explanation:
Let us assume the number as 
.
Given:
⇒ 
less than twice a number that will be 
, which is equal to half the difference of three times the number and 13
We have to find the number.
Solution:
The difference of three times the number and 13 could be represented as : 
The value be equal to 
of this ⇒ 
As we can see here,
- That we got a equation ⇒
Now, we can solve the above equation:
We have multiply both sides by 
⇒ 
then, ⇒ 
⇒ 
Hence we can say that number which was assumed as will be
Answer: no solution
Step-by-step explanation:
2x2=4x-7
4x=4x−7
0=−7
Since 0=−7 is false, the answer is no solution.
Answer:
33.45
Step-by-step explanation:
Just multiply
Just put it like normally, forget the decimal for now, you don’t have to line it up due to it not being addition Or subtraction
You’ll get 3345 without the decimal
now there are 2 decimal places from 0 so
just move the decimal place 2 times to the left
33.45
Answer:
1.646×10¹¹ km³.
Step-by-step explanation:
From the question given, we obtained the following information:
Radius (r) = 3400 km
Volume (V) =.?
The shape of a planet is spherical in nature. Thus, we shall apply the formula for calculating the volume of a sphere to obtain the volume of Planet Mar as illustrated below:
Radius (r) = 3400 km
Pi (π) = 3.14
Volume (V) =.?
Volume of a sphere = 4/3 πr³
V = 4/3 × 3.14 × (3400)³
V = 4/3 × 3.14 × 3.9304×10¹⁰
V = 1.646×10¹¹ km³
From the calculations made above, the volume of Planet Mar is 1.646×10¹¹ km³
