Answer:

A = 625π cm²

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

the circumference (C) of a circle is calculated as

C = 2πr

given C = 50π , then

2πr = 50π ( divide both sides by 2π )

r = 25

then

A = π × 25² = 625π cm²

*Will give brainiest. Tina invests $1000 in an account that pays an interest rate of 6.75%. A=P(1+r)^t.

bezimeni [28]

A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675
t= log 18.6/ log 1.0675
t=44.75 years
