What is the area of a circle with a diameter equal to 12 meters?
1 answer:
Answer:
A. 113.04 square meters
Step-by-step explanation:
Use the circle area formula, a = r².
If the diameter is 12 meters, then the radius is 6 meters.
Plug in the radius and 3.14 as pi into the formula, and solve:
a = r²
a = (3.14)(6)²
a = (3.14)(36)
a = 113.04
So, the correct answer is A. 113.04 square meters

Answer:
Anja’s phrase should have ended with “less than –15”, not “at least –15”.
Step-by-step explanation:
Given the statement:
Anja represents the inequality
with the phrase “the quotient of the difference of 4 and a number and 8 is at least –15.”
Let the number be g.
“the quotient of the difference of 4 and a number and 8" translated to
"at least" means
then;
“the quotient of the difference of 4 and a number and 8 is at least –15.” translated to
Therefore, Anja’s phrase should have ended with “less than –15”, not “at least –15”.
