Answer:
B
Step-by-step explanation:
2.5×2 + 2.5×4 + 2.5×3
Take 2.5 common
2.5(2 + 4 + 3)
The answer is B
1. 2.50 x 2 is $5
2. 2.50 x 4 is $10
3. 2.50 x 3 is $7.50
4. 5 + 10 + 7.50 is 22.50 so you know the total should be 22.50.
5. It cant be A because 2.50 x 2 is 5 then timesing that by four would make 20 and then by 3 that would make $60 not $22.50
6. It is B because 2 + 4 + 3 is 9, 9x2.50 is 22.50
230
D
Its D because A is all 90 degrees
Not C because all 90
628
So the formula is πr^2h/3
So the height is 6
pie is 3.14
Substitute:
3.14(10)^2 6/3
3.14(100)(2)
3.14(200)
628
