The radius is half the length of the diameter. So if the radius is 8 centimeters long the the diameter would be 16 centimeters long.
Answer:
(x - 8)² + (y + 9)² = 49
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (8, - 9 ) and r = 7 , then
(x - 8)² + (y - (- 9) )² = 7² , that is
(x - 8)² + (y + 9)² = 49
Answer:
Base radius:
Step-by-step explanation:
Considering the cone is Right Circular Cone:
Volume of the cone =
Given :
Putting in the formula:
Multiply by '3' both sides:
Divide by '25.12' both sides:
So, the cone has base radius:
Answer:
seventeen [17]
Step-by-step explanation:
8*8=64+15*15=225 so 225+64=289 and √289=17
