Free ACT Exam Questions That Helps Candidates Pass

Area = πr2πr^2. With r=5r=5: A=π(25)=25πA=π(25)=25π. Correct answer: C. Choices A and B omit π. Choice D misapplies the formula. ACT Math circle questions require knowing area and circumference formulas by heart.

The pronoun is the object of the verb “gave.” Objective case is required: “me.” So “Sarah and me” is correct. Choice A “I” is subject case. Choice C “mine” is possessive. Choice D “myself” is reflexive, unnecessary here. On ACT English, test-taking strategy: remove the other subject—“The teacher gave me practice problems” is correct.

The control (no fertilizer) produced 3.8 kg per plant. Fertilizer A increased this to 4.5 kg, and Fertilizer B increased it to 5.2 kg. Both are higher than control, so both improved yield. Choice A is correct. Choice B is false because A improved yield. Choice C contradicts the data, since B raised yield. Choice D is incorrect; Fertilizer B outperformed A, not vice versa. On ACT Science, always compare experimental groups to the control to evaluate effectiveness. The correct interpretation is that both fertilizers boosted production relative to no fertilizer, though B produced the largest gain.

Substitute: f(−3)=(−3)2+2(−3)+1=9−6+1=4f(-3)=(-3)^2+2(-3)+1=9-6+1=4. Correct answer: B, not D. Always substitute carefully and simplify step by step. ACT Math frequently tests substitution into functions—watch signs carefully.
