Step-by-step explanation:
large is 3 times larger than medium.
2 1/4 × 3 = 6 3/4
large is 6 times larger than small.
1 1/8 × 6 = 6 6/8 = 6 3/4
medium is 2 times larger than small.
1 1/8 × 2 = 2 2/8 = 2 1/4
About 3 gallons of blue paint will be needed because if you add 175+175 it equals 350 and then add another 175 it equals 525.
Answer:
Step-by-step explanation:
The general equation of a sphere is as follows:
In which the center is , and r is the radius.
In this problem, we have that:
So
Interior contained in the first octant:
The first octant is bounded by:
The xy plane, in which z is 0. The distance from the center of the sphere to the xy plane is 9.
The xz plane, in which y is 0. The distance from the center of the sphere to the xz plane is 4.
The yz plane, in which x is 0. The distance from the center of the sphere to the yz plane is 5.
This means that if the radius is higher than four, the sphere will cross into a different octant.
So the radius for the largest sphere is 4.
The equation is
