Answer:
Step-by-step explanation:
base length b = 3 in
slant height L = 3 in
base area = b² = 3² = 9 in²
lateral area = 4·½bL = 4·½·3·3 = 18 in²
surface area = base area + lateral area = 27 in²
Answer:
x = 16
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+2) * 2 = 6^2
2(x+2) = 36
Divide each side by 2
x+2 = 18
Subtract 2
x+2-2 = 18-2
x = 16
Answer:
D - (-2)^2 does not equal to -4
Step-by-step explanation:
√-4 does not equal -2 because if you try squaring -2 you will get 4 not -4, because 2 negative number makes it a positive.
For example
-2 x -2 - There are two negative numbers, so it should equal...
4
