Step-by-step explanation:
v.of cylinder= (pi)r²h
pi used = 22/7
first cylinder (A)= 22/7 x 5² x 7
= 550 cm3
second (B) = 22/7 x 10² x 5
=1571.43 cm3
A + B = 2121.43 cm3
new cylinder:
22/7 x r² x 3= 2121.43 cm3
r² = √2121.43/ (22/7 x 3)
r = 15 cm

I think the answer is 300 or over 300. Maybe even 750, I'm not really sure
Answer: It will cost him $237 to seed the entire backyard
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the area of the rectangular backyard:
Area of a rectangle = length x width
Replacing with the values given:
A = 20 x 15 = 300 ft2
Since seed cost 0.79 per square foot, we simply have to multiply that price by the area:
0.79 x 300 = $237
It will cost him $237 to seed the entire backyard
