Answer:
90 feet
Step-by-step explanation:
you take the length times the height to get the area
Answer:
(the last option)
Step-by-step explanation:
Hope this helps
The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use.
When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle.
Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12.
For numbers 13-15: use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!
Let me know if you still need help after this:) happy math solving!
Answer:
V = (119.27 in²)(6 in) = 235.26 in³
Step-by-step explanation:
First find the area of the half circle (face only) and the area of the (face only) rectangular prism base.
The radius of this circle is 5 in, so half the area of this this circle is:
A1 = (1/2)π(5 in)², or approx. 39.27 in²
The face area of the rectangular prism is (8 in)(10 in) = 80 in²
So the total, combined face area of this solid is 119.27 in².
Now multiply this result by the depth of the solid, which is 6 in. The result is the volume of the solid: V = (119.27 in²)(6 in) = 235.26 in³
Answer:
x + y ≥ 20
3x + 5y > 60
Step-by-step explanation:
Let
Bags of candy corn = x
Bags of chocolate = y
Cost of bags of candy corn = $3
Cost of bags of chocolate = $5
He needs to buy at least 20 bags of candy and he cannot spend more than $60
system of linear inequalities to model the situation.
x + y ≥ 20
3x + 5y > 60
The system ot inequalities which models the situation
x + y ≥ 20
3x + 5y > 60
