Answer:
V= 452.39cm³ (to 2 d.p. )
S.A. = 326.73cm² (to 2 d.p. )
Step-by-step explanation:
Vcylinder = π r² h = π (4)² (9) = 144 π = 452.3893421cm³ = 452.39cm³ (to 2 d.p. )
S.A. cylinder = 2π r h + 2π r² = 2π (4)(9) + 2π (4)² = 104π = 326.725636cm² = 326.73cm² (to 2 d.p. )

Answer:
The number of chocolate made donuts is 40 more than cream filed donuts
Step-by-step explanation:
Given as :
The number of chocolate donuts made = 48
The number of chocolate donuts is 6 times the number of cream filled donuts
So, Let the number of cream filled donuts = x
So, number of chocolate donuts made =
∴
= 48
Or, x =
= 8
So, the number of cream filled donuts = 8
Now ,
The number of chocolate donuts made - the number of cream filled donuts = 48 - 8 = 40
So , The number of chocolate made donuts is 40 more than cream filed donuts Answer
Good question
It seems that it needs to solve for "h"
Right....
<span>A=bh/2 *2
2A = bh </span>÷b
2A/b = h

hope you can pick the correct chocie
