7. Solve the inequality.
-30>-4a+18-2(2^3-a)

a ≥ 16

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

Step 2: Flip the equation.

Step 3: Subtract 2 from both sides.

Step 4: Divide both sides by -2 and flip the sign.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
