Answer:

r = 7.5

Step-by-step explanation:

Circle equation: $(x - h)^2 + (y - k)^2 = r^2$

Since we are already give <em>r²</em>, we simply just take the square root of 56.25, and we should get 7.5 as our final answer!

Answer:

The answer is 324π m².

Step-by-step explanation:

Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius :

$radius = diameter \div 2$
