Answer:
b
Step-by-step explanation:
r=d/2=11.4/2=5.7
slant surface area=2πr*h=11.4×3.14×4.4=157.5024 cm^2
area of base and top=2(πr²)=2×3.14×(5.7)²=204.0372 cm²
total surface area=157.5024+204.0372=361.5396=361.5 sq. cm
6 consecutive even numbers...x, x + 2, x + 4, x + 6, x + 8, x + 10
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 126
6x + 30 = 126
6x = 126 - 30
6x = 96
x = 96/6
x = 16
x + 2 = 16 + 2 = 18
x + 4 = 16 + 4 = 20
x + 6 = 16 + 6 = 22
x + 8 = 16 + 8 = 24
x + 10 = 16 + 10 = 26
ur numbers are : 16,18,20,22,24,26
The vertex form is
where a is the coefficient, and (h,k) is the vertex. Looking at the graph, we see that the vertex is (-2,2), so h is -2 and k is 2. We see that the parabola opens upwards, so A is positive, and is stretched by a factor of 3. (We can find this by looking where the (1,1) should be. We go over 1 from the parabola, and see where the y coordinate is. This is at (-1,5), or 1 unit right and 3 units up.) Therefore, our a is 3. Plugging this into the vertex form:
Which is answer A
Answer:
Since you didn't give anything to chose from I will just tell you the radius and then when you can do is if you have a paper or anything like that with the equation on it you find the answer by which one is closest to my answer..
