Cone=cup:
V=124<span>cm^3.
h=12cm
V=Bh
P=r</span>^2π+rsπ:
B=r^2π
B=V/h=124/12=10,3cm^2
r^2=B/π
r=√(B/π)=1,81 cm
S=√(r^2+h^2)=√(12^2+1.81^2)=√(144+3,28)=12,13 cm
P=r^2π+rSπ=3,28*3,14+1,81*12,13*3,14=10,29+68,93=79,22 cm^2
Answer:
The first graph, answer choice A.
Step-by-step explanation:
40 because 3+6+12 = 21 and 8+11+21 =40
Answer:
x=120
Step-by-step explanation:
a vertical angle is equal to each other so if angle J is 120° the so is angle K
