Answer:
(22/7)/6=0.523809
Step-by-step explanation:
V=4/3πr^3
V=4/3π(1/2)^3=π/6
or (22/7)/6=0.523809
Answer:
The area of circle 1 is 9 times greater than area of circle 2.
Step-by-step explanation:
Given that:
Radius of circle 1 = 12
Area of circle 1 = πr²
Area of circle 1 =
Area of circle 1 = 452.16
Radius of circle 2 = 4
Area of circle 2 =
Area of circle 2 = 50.24
Let,
x be the number of times circle 1 is bigger than circle 2.
Area circle 1 = x * Area circle 2
Hence,
The area of circle 1 is 9 times greater than area of circle 2.
188 is the answer of questions
Answer:
b) The measure of angle B is 117°.
Step-by-step explanation:
Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...
∠C = 90° -27° = 63° . . . . . not 53°
The measure of angle B is the supplement of angle A or C, so is ...
∠B = 180° -∠C = 180° -63°
∠B = 117°
Only choice B is correct.
