What is the equation of a circle centered at the origin with radius 20​

we have a rule

(x-h)²+(y-v)²=r²

while h is the x intercept

v is y intercept

r is the radius

so the answer will be

x²+y²=400

or

x²+y²=20²

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
