Answer:
12.25
sq m
Step-by-step explanation:
if circumference is 7
then the diameter is 7
Area =
r²
A = (3.5)²
A = 12.25

Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
Answer:
D: 25 miles
Step-by-step explanation:
Pythagorean Theorem:

36^2 + b^2 = 39^2
1,296 + b^2 = 1,521
b^2 = 225
b = 25
