Answer:
$1500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 20%/100 = 0.2 per year,
then, solving our equation
I = 500 × 0.2 × 10 = 1000
I = $ 1,000.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 20% per year
for 10 years is $ 1,000.00.
The formula for the volume of a sphere of radius r is V = (4/3)(pi)r^3.
Here, with r = 3 in, the volume is
V = (4/3)(3.14)(3 in)^2, or V = 36(pi)(27 in)^3 = 36pi in^3
x=20

it is the square + the circle
15*25+πr²
375+π(15/2)²
375+π225/4
375+176.625=551.625
