Answer:
<u>circumference = 12.56 m.</u>
Step-by-step explanation:
circumference of a circle is the distance around the circle or the perimeter of the circle.
the diameter is two times the radius
d = 2 r
circumference = 2 π r = π (2r) = π d
Given: diameter = d = 4 and π = 3.14
<u>∴ circumference = 4 * 3.14 = 12.56 m</u>
The answer is B.) one of the numbers is negative.
So if you take the example...
-3 x -7 = 21
then we know that they equal a positive.
21 ÷ -3 = -7
Answer:
3.3 lb ≤ Weight ≤ 4.1 lb
Step-by-step explanation:
The options are not given; however, the question can still be solved.
Given
Weight = 3.7 lb
Range = 0.4 lb
The possible weight is calculated by (1) & (2) below
1. Maximum
Maximum = 3.7 lb + 0.4 lb
Maximum = 4.1 lb
2. Minimum
Minimum = 3.7 lb - 0.4 lb
Minimum = 3.3 lb
Hence, the range the weight of the apple can be is
3.3 lb ≤ Weight ≤ 4.1 lb
Answer:
∠ B ≈ 62.73°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinB = 
= 
= 
, thus
∠ B = 
( ) ≈ 62.73° ( to the nearest hundredth )
