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:
103°
Step-by-step explanation:
The law of sines tells you ...
sin(C)/c = sin(A)/a
sin(C) = (c/a)sin(A)
C = arcsin(c/a·sin(A)) = arcsin(37/19·sin(30°)) ≈ 180° -76.8° ≈ 103°
Obtuse angle C is about 103°.
