Answer:
A) 28 m^2
Step-by-step explanation:
(4x4) + (3x4) = 28 m^2
The mean is 14
add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.
12+10+14+18+14+16
= 84
84/6 = 14
Answer:
Yes, the number 400 is a perfect square. A perfect square is a number that can be expressed as the product of two equal integers.
Step-by-step explanation:
Answer:
67.014
Step-by-step explanation:
V = π r^2 (h/3)
(Volume equals pi r squared, h over 3)
Diameter is 4, so the radius is half of that = 2
Plug in the numbers
V = π (2^2) (16/3)
V = π (4) (5.333)
V = 3.14 x 4 = 12.566
V = 12.566 x 5.333
V = 67.014
I think it's the third 4 ( а² + 2а ) + 9
