Answer the question for brainilest and 50 points

in terms of pi

1.A = 225 π ft2

2.A = 121 π in2

3.A = 81 π yd2

4.A = 36 π yd2

5.A = 9 π in2

6.A = 289 π ft2

7.A = 100 π ft2

8.A = 64 π in2

9.I didn't understand it

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
