Surface Area of a sphere, A grapefruit with C = 14cm.

9966 [12]

Surface area SA: $4\pi r^2$
Circumference C: $2\pi r$ dividing this you get $7=\pi r$ and $r= \frac{7}{\pi}$

Now let's input the radius $r$ into the Surface area formula...
$4\pi r^2\rightarrow 4\pi(\frac{7}{\pi})^2=4\pi(\frac{49}{\pi^2})=\frac{196}{\pi}$

I need help on this please

When it's laid out like that. 2 division statements on either side with one unknown variable you just cross multiply really easy

5 x 24 / 6 = 20

Take the number that's on the same position of the x thats 5 then multiply it to the numerator or denominator of the x thats 24 then divide it to its denominator thats 6
