Answer:
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle
π is a constant whose value is 3.14
From the information given,
Radius = 6 cm
Therefore,
Circumference = 2 × 3.14 × 6
Circumference = 37.68 cm
The formula for determining the area of a circle is expressed as
Area = πr²
Area = 3.14 × 6² = 113.04 cm²
It’s probably A. (1,2) hope this helps..
There are 13 protons because the atomic number (the number in the top left corner) represents the number of protons. Then, to find the number of neutrons, you take the number of protons and subtract it from the atomic mass (the number on the bottom) when it is rounded. The number of electrons is the same as the protons when the atom is neutral
Answer:
$10000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 2000 / ( 0.05 × 4 ) = 10000
P = $ 10,000.00
The principal required to
accumulate interest of $ 2,000.00
on a rate of 5% per year for 4 years is $ 10,000.00.
