8/12 is .67, when rounded. In order to find her percentage, multiply .67 by 100 to get it. She got 66.7%, when rounded, on the test.
Answer:
two and one fifth
Step-by-step explanation:
Sphere Volume = <span> 4/3 • <span>π <span>• r³
r^3 = sphere volume / (4/3 * PI)
r^3 = 288*PI / (4/3 * PI)
</span></span></span><span>r^3 = 288 / (4/3)
</span>r^3 = 216
r = 6 inches
Sphere Surface Area = <span> 4 • <span>π <span>• r²
</span></span></span>
Sphere Surface Area = 4 * PI * 36
Sphere Surface Area =

Answer:
676π Sq. cm.
Step-by-step explanation:
The line GY is the radius of the circle with G as center and Y is a point on the circle.
Now, GY = 10 cm.
Again, the line XY is the radius of the circle with X as center and Y is a point on the circle.
Now, XY = 16 cm
The two circles touched at point Y,
Therefore, point Y will be on line GX.
Now, GX = GY + YX = 10 + 16 = 26 cm.
Therefore, Marco wants to create a new circle using GX as the radius, then the area of the new circle will be π (26)² Sq. cm. = 676π Sq. cm. (Answer)
