The circumference of the grape fruit is 2\pi r=14, where r is the radius. Solving for r,

r=\frac{7}{\pi}.

The surface area of a sphere with radius r is S=4 \pi r^2. Substituting numerical value of r,

S=4 \pi r^2 =4 \pi (\frac{7}{\pi}  )^2  =62.39.

The surface area of the grape fruit is 62.39\;cm^2.

Answer:

50 cm^2

Step-by-step explanation:

area of rectangle = base * height

5 * 7 = 35

area of triangle = base * height / 2

5 * 4 = 20/2 = 10

5 * 2 = 10/2 = 5

add them all up

35 + 5 + 10 = 50 cm^2

What is the x-intercept of the equation -7x+3y=21
mezya [45]
Hello!!

Well, the x-intercept is found when y = 0, so plug in y = 0:

-7x + 3(0) = 21
-7x = 21
x = -3

Therefore, the x-intercept of -7x + 3y = 21 is -3.

Hope this helps!! Let me know if you have ANY questions.
