Answer:
452cm2
Step-by-step explanation:
surface area of sphere =4πr2
so 4π62 which equals to 452.39.
hope this helps u understand:)
Reversing the clauses of an "if-then" statement only sometimes makes the new statement true, so it isn't true or false. For example, reversing the clauses of "if 1=x, then x=1" makes the new statement true, but reversing the clauses of "if x=2, then |x|=2" doesn't.
Answer:
6y^2+7
Step-by-step explanation:
when you put in the two for y you get tour answer. i tried to simplify it down to the simplest form.
Cost of one daylily is $2 and cost of one geranium is $4.
Step-by-step explanation:
Let,
Cost of one daylily = x
Cost of one geranium = y
According to given statement;
x+5y=22 Eqn 1
13x+y=30 Eqn 2
From Eqn 1;
x=22 - 5y
Putting this value of x in Eqn 2;
Dividing both sides by -64
Putting y=4 in Eqn 1
Cost of one daylily is $2 and cost of one geranium is $4.
