Hello There!
Surface area of a sphere formula:
4πr²
SA = 4π14.21²
SA = 2537.5mm³
Surface area of a cone formula:
1/3πr²5
SA = 1/3π3²15.1
SA = 142.3in³
Pyramid:
SA = 124.3
Hope This Helps You!
Good Luck :)

Answer:
25 feet
Step-by-step explanation:
Given that Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?
To calculate the length of the kite string, we will apply pythagorean theorem.
Length = sqrt ( 20^2 + 15^2 )
Length = sqrt ( 400 + 225 )
Length = sqrt ( 625 )
Length = 25 feet.
Therefore, the length of the kite string is 25 feet.

The top one is 1
Step-by-step explanation:
Answer:
7 km
Step-by-step explanation:
Substitute:
The equation for area of a semi-circle is 
A = 
76.97 = 
Multiply by 2 on both sides:
2(76.97) = (
)2
153.94 = 
Divide by pi on both sides:
153.94 = 
/pi /pi
49.03 ≈ 
Find the square root:
