Answer:
30
Step-by-step explanation:
Plug in x:
6(5)=30
The given circumference is C = 12*pi
The formula for the circumference of any circle, with radius r, is
C = 2*pi*r
Plug in the given value of C and solve for r
C = 2*pi*r
12*pi = 2*pi*r ... C has been replaced with 12*pi
12 = 2*r ... divide both sides by pi (they cancel out)
6 = r ... divide both sides by 2
So r = 6 is the radius
Answer: $59313.58
Step-by-step explanation:
Formula to find the accumulated amount of the annuity is given by :-
, where A is the annuity payment deposit, r is annual interest rate , t is time in years and m is number of periods.
Given : m= $2000 ; m= 1 [∵ its annual] ; t= 10 years ; r= 0.06
Now substitute all these value in the formula , we get
⇒ 
⇒ 
⇒ 
⇒ ![FV=59313.5772407\approx59313.58 \ \ \text{ [Rounded to the nearest cent]}](https://tex.z-dn.net/?f=FV%3D59313.5772407%5Capprox59313.58%20%5C%20%5C%20%5Ctext%7B%20%5BRounded%20to%20the%20nearest%20cent%5D%7D)
Hence, the accumulated amount of the annuity= $59313.58
To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8
Answer:
The surface area of cone = 54π cm²
Step-by-step explanation:
Given ;
Radius = 3 cm
slant height = 15cm
The surface area of cone = πr ( r + l )
=> π × 3 ( 3 + 15)
=> π × 3 ( 18)
=> 54 π cm²
