Answer:
number 4 is 244 number 5 is 43
Step-by-step explanation:
order of operations is key here
4:6 to the power of 3 is first
216+7*4
now do 7*4
216+28
now simplify
244
5: this one is a little bit more tricky
do the stuff inside the parentheses first
4^2+1=17
3(17)-2^3
exponent next
3(17)-8
multiply next
51-8
43 is your answer
there you go
Answer:
22 and 26
Step-by-step explanation:
for the area of the smaller semicircles
area = 1/2 x 3.142 x 5 x 5
area = 39.275cm²
for the larger circle
area = 1/2 x 3.142 x 10x 10
area= 157.1cm²
but since part of it is out and is replaced again
..total area of shaded part is 157.1cm² + 39.275cm² - 39.275cm²
area =157.1cm²
