Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )

Answer:
C. 1
Step-by-step explanation:
The lateral area is given by the formula ...
LA = 2πrh
Filling in the given values, you have ...
8π = 2π·r·4
1 = r . . . . . . . . divide by the coefficient of r
The radius of the cylinder is 1 foot.
Answer:
x = 10
Step-by-step explanation:
<u>Complementary angles mean 90 degree angle.</u>
Angle P + Angle Q = 90°
Angle P ---> 29°
Angle Q --> 6x + 1
<u>Find x</u>
Angle P + Angle Q = 90°
29 + 6x + 1 = 90°
30 + 6x = 90
6x = 90-30
6x = 60
x = 60/6
x = 10
Therefore, the value of x = 10.
Angle Q = 6x + 10 --> 6(10) + 1 --> 61°

Step-by-step explanation:
Answer:
7/9 + (-7/9) = 0
Step-by-step explanation:
Definition of additive inverse:
Two numbers are additive inverses if their sum is zero.
For example, 2 and -2 are additive inverses since 2 + (-2) = 0.
Now your problem:
7/9 + (-7/9) =
7/9 and -7/9 are additive inverses.
Therefore, their sum is 0.
7/9 + (-7/9) = 0
