Answer:
radius is 3.38cm
Step-by-step explanation:
Note: the volume of a cone is given as

Step one:
Given Information
volume= 30cm^3
height= 2.5cm
Required
The radius of the cone
Step two:
substituting our data into the expression for the volume of a cone we can then solve for the radius r

divide both sides by 2.62

Answer: the correct option is A
Step-by-step explanation:
Cost of the bus is $25000. She took a loan of $25000 to be paid of in 5 years at an interest rate of 7%.
The formula for simple interest is expressed as
I = PRT/100
Where
I = interest
P = principal or initial amount borrowed
T = time in years
R = interest rate in percentage
From the information given,
P = 25000
R = 7%
T = 5 years
Therefore
I = (25000 × 7 × 5)/100 = 875000/100
I = $8750
Thirty three because I'm just smart like that so you should believe me entirely.
