Answer:
[C] 25π square inches
Explanation:
Given that:
the long hand of the clock is about 5 inches long.
To Find:
What is the approximate area of the clock face?
Solve:
Formula - A =πr²
Note that;
π = 3.14 (about)
Radius - 5 inches
A =πr²
A = 3.14(5)²
A = 3.14(25)
A = 78.5
Now let see the answer choices:
A. 5π square inches ≈ 5(3.14) = 15.7
B. 10 π square inches ≈ 10(3.14) = 31.4
C. 25 π square inches ≈ 25(3.14) = 78.5
D. 100 π square inches ≈ 100(3.14) = 314
Hence, the answer is [C] 25 π square inches
