Step-by-step explanation:
This is the concept of areas of solid materials; the surface area of the cylinder whose radius is 2.5 cm and lateral area is 20 pi cm^2 will be: Surface area of cylinder is given by:
SA=(area of cyclic sides)+(lateral area)
SA=2πr^2+πrl
Area of the cyclic sides will be:
Area=2πr^2
=2*π*2.5^2
=12.5π cm^2
The lateral area is given by:
Area=20π cm^2
Therefore the surface area of cylinder will be:
SA=(12.5π+20π) cm^2
SA=32.5π cm^2
The answer is 32.5π cm^2

Answer:
130 yd^2
Step-by-step explanation:
First we find the area of the triangle
A = 1/2 b h where b is 10 and h= 6.25
A = 1/2 (10) * 6.25
= 31.25 yd^2
Then we find the area of rectangle A
A = l*w where l is 10 and w = (7.5-2.5) = 5
A = 10 * 5
= 50 yd^2
Then we find the area of rectangle B
A = l*w where l is 6.5 and w = 7.5
A = 6.5 * 7.5
= 48.75 yd^2
The total area is found by adding them together
A triangle + rectangle A + rectangle B
31.25+50 + 48.75
130 yd^2
Answer:
Lourdes has more brownies.
Step-by-step explanation:
First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.
24/30 < 25/30. So Lourdes has the most brownies!
