Answer: 1296π
Step-by-step explanation:
To find the surface are if a square, we have to use the formula:
= 4πr²
= 4 × π × 18²
= 4 × π × 324
= 1296π
Therefore, the surface area of the sphere is 1296π
These patterns are similar because in both the number of dots are increasing. they are different because the pattern in the first one is adding 2 each step, while in the second one you are taking the starting amount, multiplying it by 2 then adding 1. to find the number of dots for step 5 you would add 2 in the first pattern, in the second pattern multiply by 2 add 1.
Answer:
Then what is the radius of the circle? Since, the tangent of any point of a line is perpendicular to the radius through the point of contact. Hence, radius of the circle = 8 cm.
<span>y = 3x + 1 because if you put it on a graph it is the one that comes out straight so therefore it is a linear function.</span>
37/4 is the first one and 15/3 is the second one. All you have to do it multiply the coefficient in front of the fraction by the denominator and add that number with numerator.
