The circumference is 2pi*r=5.,38
 ⇒ r= 53.38/pi=53.38/3.14= 17

The area is pi*r^2= 3.14*17^2=907.46

A=907.46

Answer:

300ft^3

Step-by-step explanation:

I'm guessing what the question meant be triangular is a triangular prism.

The volume formula for a triangular prism is 1/2(lwh)

L=10

W=10

H=6

(6)(10)(10)=600

600/2=300

V=300ft^3

Hope this helps! :)

Claire invests £200,000 in a savings account for 4 years. The account pays a compound interest of 1.6% annum. Calculate the tota
AURORKA [14]

Answer: total amount of interest = £13110.49

Step-by-step explanation:

given that the

Principal P =  £200,000

Time t = 4 years.

Rate R = 1.6% 

Amount = P( 1 + R% )^t

Amount = 200000( 1 + 1.6%)^4

Amount = 200000 (1.016)^4

Amount = 200000 × 1.06555245

Amount = £213110.49

The total amount of interest = amount - principal

Total amount of interest = 213110.49 - 200000

The total amount of interest = £13110.49

Therefore, Claire will get a total amount of interest of £13110.49 at the end of four years
