Answer:
394.1 m
Step-by-step explanation:
The length of the track will be the two sides of 95 plus one complete circumference of the two semi-circles.
That circumference is pi*65.
So the total length is 2*95+65pi = 394.1
Answer:
r = 4
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
V = 100.48
h = 6
π = 3.14
Work:
V = πr²(h/3)
100.48 = r²(3.14)(6/3)
100.48 = r²(3.14)(2)
100.48 = r²6.28
r² = 100.48/6.28
r² = 16
r = 4

Answer: 3 × 10⁴ miles²
Step-by-step explanation:
Given that:
Estimated Surface area of Lake = 30,000 square miles
Expressing the estimated area as a whole number multiplied by a power of ten
Hence, we are required to express the surface area in standard form:
30,000 miles ² in standard format:
30,000 is equivalent to (3 × 10,000)
3 is a whole number
10,000 = (10 * 10 * 10 * 10)= 4 th power of 10
10,000 = (10 * 10 * 10 * 10) = 10⁴
Hence,
3 × (10 * 10 * 10 * 10) = 3 × 10⁴ miles²
