Answer:
centre = (0, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 25 ← is in this form
with centre = (0, 0 ) and r = 
= 5
Answer:
(1436.8cm³) let me know if that helps
Step-by-step explanation:
-so if the diameter is a straight line and it's 15 cm
-The formula for the sphere it would be v=4/3πr³
-The radius is going to be r=7cm
-v = 4/3 π (7cm)³
-so you would type in 4/3 x 3.14 x 7 ³ =1,436
- 3.14 or π
- you would round it to the nearest 10th (1436.8cm³)
Answer:
X^2-2X+1=0
Step-by-step explanation:
given,2X-X^2=1
or,-(X^2-2X)=1
or,X^2-2X=-1
or,X^2-2X+1=0 ,which is the req.equation in standard form.
