P= 30ft
Step-by-step explanation:
Hi there!
Find the volume of a sphere using the following equation:
V = 4/3πr³
Substitute in the given radius:
V = 4/3π(1)³
V = 4/3π or ≈ 4.19 units³
Answer:
14
Step-by-step explanation:
f(x)=2x+7
f(4)=2(4)+7
=8+7
=15
f(-4)=2(-4)+7
=-8+7
=-1
f(4)+f(-4)
=15+(-1)
=14.
Answer:
3
Step-by-step explanation:
5x-22 = -7
5x=15
x = 3
Answer:
AB = 3.5π
Step-by-step explanation:
The length of arc AB is calculated as
AB = circumference of circle × fraction of circle
= 2πr × ( r is the radius and r = 7 )
= 2π × 7 ×
= = 3.5π
