Surface area of sphere=100pi cm^2
4pi×r^2=100 pi
pi cancel on both sides
4×r^2=100
r^2=100/4
r^2=25
so r=5
So option b 5 cm is correct.
Answer:
the answer would be 1 since 10 can only go into 10, 1 time
Step-by-step explanation:
There are 3 × 4 = 12 pieces total
14 × 1/4 = 3.5 pizzas needed
not enough, you need two more slices
Answer: 0 radians
Explanation: Looking at the unit circle, tan and sin equal each other at 0 radians. Sin(0) = 0 and tan(0) = 0/1 = 0.
Therefore, theta equals 0. Multiplying by 3 does not matter in this case because it is being multiplied by 0. Any number multiplied by 0 is 0.
