Answer:
A) 113 m²
Step-by-step explanation:
Use the formula for area of a circle.
Area of a circle = πr²
π = pi = 3.14 (rounded)
r = radius
² = the power of 2, or the radius (in this case) multiplied by itself.
Note that the radius is given, and it is 6. Plug in 6 for the radius:
A (circle) = π(6)²
First, solve the power. Multiply 6²:
6² = 6 * 6 = 36
Next, multiply 36 with π (3.14):
36 x 3.14 = 113.04
A) 113 m² is your closest answer.

Answer:
1. No, Joe is not correct
2. 
Step-by-step explanation:
Given: b and c are parallel lines
To find:
1. whether the given statement is correct or not
2. 
Solution:
1.
Sum of two angles that form a linear pair is equal to 
(linear pair)
So, Joe is not correct
2.
If two lines are parallel then alternate interior angles are equal.
As b and c are parallel lines,
(alternate interior angles)
The primes are 2, 3, 5, 7, 11, 13, 17, 19. There are 8 of them, so they make up 40% of the numbers 1–20.
Answer:
Ms D left at 6:40 AM
Step-by-step explanation:
Given:
MS D arrived at school at 7:30 AM
time spent for dinner = 35 mins
Time taken to to go to school = 15 mins
We will first find the Total time taken after leaving.
Total time taken can be calculated by adding time spent for dinner and Time taken to to go to school.
Total time taken after leaving = time spent for dinner + Time taken to to go to school = 35 +15 = 50 mins
MS D arrived at school at 7:30 AM.
Hence Time Ms D left = Time She arrive at school - Total time taken after leaving = 7 hrs 30 min - 50 mins = 6 hrs 40 mins.
Hence Ms D left at 6:40 AM.
