Find the surface area of a sphere with a great circle that has an area of 49 π square miles.
Mademuasel [1]
The answer is <span>B. 196 π mi2
</span>
(1) Find radius r:
The area of the circle is:
A = r²π
A = 49π mi²

49π = r²π
49 = r²
r = √49 = 7 mi

(2) Find the surface area of the sphere.
The surface area of the sphere is: 
A = 4πr²
r = 7 mi
A = 4π * 7²
A = 4π * 49
A = 196π mi²

Help thanks in advance !
lutik1710 [3]

Answer:

Take your product denominator and divide it by the original. 48÷8=6

Since the denominator was increased by a scale factor of 6, the numerator must also be increased by a scale factor of 6 in order to keep the 2 fractions equal. 7×6=42

Hence, your answer is 42/48

Hope this helps?

Question 40 and it about adding and subtracting polynomials
kolbaska11 [484]

Answer:

39x-7

Step-by-step explanation:

The perimeter is all the sides added together so

9x + 8x - 2 + 5x + 1 + 17x - 6

Since you can't solve it you just want to simplify the equation, add the like terms together

9x+8x+5x+17x = 39x

-2+1-6 = -7

Your equation is 39x-7
