Answer for x would be 4. the area of the circle would be approx. 28.3.
Divide 48 by 3, for every three 8th graders, there is one 7th grader in choir
48÷3=16
There's 16 7th graders in choir !!
Answer:
Step-by-step explanation:
You have a half sphere and a cylinder.
Trick question! Note that the diameter of the cylinder is in meters, while the height is given in centimeters.
For cylinder:
radius r = 5 m
height h = 6 cm = 0.06 m
volume = πr²h = π(5²)(0.06) = 1.5π m³
For sphere:
radius r = 5 m
volume of sphere = (4/3)πr³
volume of half sphere = (2/3)πr³ = (2/3)π5³ = (250/3)π m³
Total volume = 1.5π + 250π/3 ≅ 266.5 m³
Answer:
26.14
Step-by-step explanation:
For the triangles: 3*4=12
For the circle: 28.27/2=14.135
12+14.135=26.135
~26.14
46 -2c
46 decreased by means 46 minus
Twice c would be c times 2
