Katrina uses place value to find the sum of 627+ 361. she begins by breaking the problem into smaller problems. she writes (600+ 300)+ (20 +60) (7 +1). which shows the correct sums of the hundreds, tens, and ones? a. 800+80+9 b.800+90+8 c.900+80+8 d.900+90+8

600 + 300 = 900
20 + 60 = 80
7 + 1 = 8

C. 900 + 80 + 8

The answer is 2,713 in³

The volume (V) of the prop is the sum of the volume of cone (V1) and half of the volume of the sphere (V2): V = V1 + 1/2 * V2

Volume of the cone is:
V1 = π r² h / 3
According to the image,
h = 14 in
r = 9 in
and
π = 3.14
V1 = 3.14 * 9² * 14 / 3 =  1,186.92 in³

The volume of the sphere is:
V2 = π r³ * 4/3
According to the image,
r = 9 in
and
π = 3.14
V2 = 3.14 * 9³ * 4/3 = 3,052.08 in³

The volume of the prop is:
V = V1 + 1/2 * V2
V = 1,186.92 in³ + 1/2 * 3,052.08 in³
V = 1,186.92 in³  + 1,526.04 in³ 
V = 2,712.96 in³ ≈ 2,713 in³
