Answer:
surface area = 245.04 cm² (nearest tenth)
Step-by-step explanation:
Surface area of a closed cylinder = 
Given:
- diameter = 6 cm ⇒ radius = 3 cm
- height = 10 cm
⇒ surface area = 2 ×
× 3² + 2 ×
× 3 × 10
= 78
= 245.04 cm² (nearest tenth)
Answer:
x=24
Step-by-step explanation:
x + 0.07x = 25.68
1.07 x = 25.68
x = 24
Answer:
for every 1000 people, the maximum noise level goes up by 1.5
Take 1 to the other side as negative
p/2=2
Take 2 to the other side and multiply it
2*2 is 4
So p is 4
Answer:
expand (a + 7) * 2: 2a + 14
Step-by-step explanation:
(a + 7) * 2
= 2 ( a + 7)
apply the distributive law: a(b + c) = ab + ac
a = 2, b = a, c = 7
= 2a + 2 * 7
multiply the numbers: 2 * 7 = 14
= 2a + 14
