Answer:
SA = 615.4 yd²
Step-by-step explanation:
The surface area (SA) of a sphere is calculated as
SA = 4πr² ← r is the radius
Here diameter = 14, thus r = 14 ÷ 2 = 7, then
SA = 4π × 7² = 4π × 49 = 196π = 196 × 3.14 ≈ 615.4 yd²
Subtract 1:
x/4=2
multiply by 4:
x=8 which is the answer
Distribute the 4 into the parenthesis by multiplying the numbers by 4.
New expression is:
24m-28
