What is the area of a circle with a radius of 5 ft? Use 3.14 for pi.
A
10\piπ sq. feet

B
25\piπ sq. feet

C
31.4 sq. feet

D
78.5 sq. feet

Answer

D) 78.5 sq. feet

Step-by-step explanation:

circle area formula is π * r^2, so  (3.14) * (5)^2 = 3.14 * 25 = 78.5

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.

this is impossible to do there is no way you can convert 35/4 into an improper fraction because it already is an improper fraction but you can simplify 35/4 = 8 3/4 or in a decimal 8.75.

hope i ! have a great rest of your week!
