1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
Answer:
Step-by-step explanation:
Do you mean 27 units² ?
A cube has six congruent, square faces. Area of one face = (27/6) units²
Length of one edge = √(27/6)
= √(9/2)
= √9/√2
= 3/√2
= 3√2/2 units
Answer:
82°
Step-by-step explanation:
total wine of quadrilateral=360°
130+ 46+ 102 +x =360
x=360- 278
x=82°
Answer:
3/5
Step-by-step explanation:
60% to a decimal is 0.6
0.6 to a fraction is 60/100
60/100 reduced is 3/5
