Sphere Surface Area     =    <span> 4 • <span>π <span>• r²

50.27 = 4 * PI * r^2
</span></span></span>
<span>50.27 / (4 * PI) = r^2

</span> <span> <span> <span> 4.0003594946 </span> </span> </span> = r^2

r = sq root (<span> <span> <span> 4.0003594946)

radius = </span></span></span> <span> <span> <span> 2.0000898716 </span> </span> </span>

So the diameter = <span> <span> <span> 4.0001797433 </span> </span> </span>

or it is roughly 4 feet

Based on the side lengths given (a, b, and c), which triangles are right triangles?
Mekhanik [1.2K]

Answer:

B & C

Step-by-step explanation:

Use the Pythagorean Theorem:   a^2 + b^2 = c^2

A) 18^2 + 24^2 = 2,088   |   42^2 = 1,764     [NOT A]

B) 33^2 +56^2 = 4,225   |   65^2 = 4,225     [B IS CORRECT]

C) 19^2 + 180^2 = (32,761) = 181^2 = (32,761)     [C IS CORRECT]

D) 3^2 + 4^2 = 25  |   7^2 = 49     [NOT D]

I hope this helped you ! In return, please deem this the most brainliest answer.

Given

Frank invests $1,000 in simple interest investment account that pays 8% a year.

After a number of years, he withdraws his balance of $2,200.

The number of years was his money inversted is;

\rm I= P\times r \times t

Where p is the principal amount, r is the rate of interest, I is the amount and  t is the time.

Substitute all the values in the formula;

\rm I= P\times r \times t\\\\2200-1000= 1000 \times .08 \times t\\\\1200 = 80t\\\\t = \dfrac{1200}{80}\\\\t=15

Hence, in the 15 years was his money invested.

Setler [38]

Answer:

=0.3 per km²

Step-by-step explanation:

Population density is the population per uni area.

Area=πr² Where A is area and r is the radius of the circle.

A=3.14×34

=106.76km²

Population density = Population/Area

=32 antelopes/106.76 km²

=0.3 per km²

The population of antelopes within the given radius is 0.3 per km²
