113.04 is the answer do u know how to get it
Here you go: the answers
7. C
8. A
-9 because-26 minus 10 is -36 and -36 divided by 4 is -9
Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
183 x 194 = 35,502
you could use a calculator or put it into the overlap form
